Added screenshot capability to the corevideo VO by sending back the raw data
from the CVPixelBuffer.
Also added "screenshot window" functionality from the other OpenGL based VOs,
which uses glReadPixels to read image data back. This was moved to gl_common to
avoid duplication.

Now both GL3 (for vo_gl3) and legacy context context creation (for
vo_gl) use the same code to create the X window. Only actual GL context
creation is different.

Now vo_gl3 should work with standard OpenGL 2.1, as long as the
GL_ARB_texture_rg extension is available. Optional features, which
require features that are always in OpenGL 3.0, but are available
as extensions only in OpenGL 2.1, are automatically disabled.
The force-gl2 suboption, which was an unreliable hack to run vo_gl3
in an OpenGL 2.1 context, is removed.
Significant changes are done to the extension loader to make it easier
to identify optional OpenGL features.
Context creation is a bit changed to simplify the code and to handle
the fallback better if OpenGL 3 context creation fails, and creating
an OpenGL legacy context is attempted.
Based on the initial work by Rudolf Polzer <divverent@xonotic.org>,
which included making the shader GLSL 1.20 compatible, and more.

makes use of it.

Useless. It complicated the code and caused flicker, and was useless
otherwise. The manpage describes this option as "should not normally
be used".
One possibly useful effect from the point of view of the user was that
vsync was disabled. You can do this with the --vsync option, or by
changing X/driver settings directly.

This also adds support for multiple EOSD renderers. This capability is
unused yet, but important for the following commits.

This transition to a new VO API started over 4 years ago. It's time to
finally end it, and get rid of the horrible hacks.
Also removes some previously undetected dead code from spudec.c.

Some of these have only limited use, and some of these have no use at
all. Remove them. They make maintainance harder and nobody needs them.
It's possible that many of the removed drivers were very useful a dozen
of years ago, but now it's 2012.
Note that some of these could be added back, in case they were more
useful than I thought. But right now, they are just a burden.
Reason for removal for each module:
vo_3dfx, vo_dfbmga, vo_dxr3, vo_ivtv, vo_mga, vo_s3fb,
vo_tdfxfb, vo_xmga, vo_tdfx_vid:
All of these are for very specific and outdated hardware. Some
of them require non-standard kernel drivers or do direct HW
access.
vo_dga: the most crappy and ancient way to get fast output on X.
vo_aa: there's vo_caca for the same purpose.
vo_ggi: this never lived, and is entirely useless.
vo_mpegpes: for DVB cards, I can't test this and it's crappy.
vo_fbdev, vo_fbdev2: there's vo_directfb2
vo_bl: what is this even? But it's neither important, nor alive.
vo_svga, vo_vesa: you want to use this? You can't be serious.
vo_wii: I can't test this, and who the hell uses this?
vo_xvr100: some Sun thing.
vo_xover: only useful in connection with xvr100.
ao_nas: still alive, but I doubt it has any meaning today.
ao_sun: Sun.
ao_win32: use ao_dsound or ao_portaudio instead.
ao_ivtv: removed along vo_ivtv.
Also get rid of anything SDL related. SDL 1.x is total crap for video
output, and will be replaced with SDL 2.x soon (perhaps), so if you
want to use SDL, write output drivers for SDL 2.x.
Additionally, I accidentally damaged Sun support, which made me
completely remove Sun/Solaris support. Nobody cares about this anyway.
Some left overs from previous commits removing modules were cleaned up.

Add support for querying the bit depth of the colors from the OpenGL
context. This allows to perform dithering correctly.

Run dlopen on the OpenGL dynamic library instead of on the binary.

Restructure this video output to be similar to vo_gl, even if simpler
and less feature complete (for example it's still missing EOSD
support). Ideally, it should act as a decent fallback in the case
where something breaks in the OSX support of vo_gl.
Here's a summary of what changed:
* Remove the shared buffer code since it wasn't using any function
from the CoreVideo API. Moreover, its presence in vo_corevideo was
forcing the non-GUI related code to perform more image copies than
necessary. Equivalent shared-buffer functionality will be added in
a separate new VO in the next commit (this means OSX GUIs will need
to specify a different VO).
* Clean up the code to conform a bit more to the mplayer2
conventions. Enforce 80 column wrapping, use a private struct for
file variables, use the new libvo api.
* Add OSD rendering using OpenGL instead of writing directly on the
video image data.
* Simplify the logic for the rendering function when dealing with
panscan.
* Add VOCTRL_REDRAW_FRAME support.
* Add colormatrix support by using the built-in API provided by
CoreVideo.

Only call glXGetClientString(), which contains all supported GLX
extensions. Extensions only returned by glXGetClientString() or
glXGetServerString() are not necessarily actually supported.
This essentially reverts svn commit 29721 (git fe3b9a88ce62ab). It is
not known whether this commit actually fixed anything, such as working
around a broken OpenGL driver.

This reflects the changes done to x11_common in mplayer2 some years
ago. It makes it possible to open multiple VOs at once.
The removed defines are probably for ancient versions of MinGW with
incomplete headers.
Remove some minor code duplication.

Remove all platform/GUI specific includes from gl_common.h. Get rid of

This new vo is heavily based on vo_gl.c. It provides better scale
filters, dithering, and optional color management with LittleCMS2.
It requires OpenGL 3.
Many features are enabled by default, so it will be slower than vo_gl.
However, it can be tuned to behave almost as vo_gl.

The code used OpenGL 3 specific functions for querying the extension
string when the actual GL 3 context wasn't created yet. This appears to
work fine on nVidia, but could break otherwise. Remove the offending
getFunctions call and retrieve the needed function pointer manually.
(This way the wglCreateContextAttribsARB function pointer can be removed
from struct GL too.)
(Amusingly exposes a wine bug; they made the same mistake.)
Explicitly check the extension string whether the function is available,
although this probably doesn't matter in practice.
Also retrieve bit depth information on win32.

Also include GL/glext.h on windows:
Mingw's (and cygwin's) GL/gl.h has GL/glext.h's inclusion commented
out for some reason. Their glext.h is also ancient, so do yourself
a favor and replace your GL/glext.h with the one from
http://www.opengl.org/registry/api/glext.h .
A workaround is needed for NVidia's broken wglCreateContextAtrribsARB:
It'll return an error if the requested OpenGL version is previous to
3.2 *and* you request a profile... which is exactly *not* what the
wgl_create_context spec says should happen.
Handle it by removing the profile request from attribs[] and retrying
the context creation once more if the first try fails.
And after my first foray into OpenGL I already find a driver quirk.
Oh well.

Also add a bunch of GL functions to the function loader, which will be
needed by vo_gl3. Remove some unused legacy GL functions from the
loader.
Use the proper name for glGetProgramivARB. glGetProgramiv is a different
and incompatible function. The ARB variant is used for ARB shaders,
while the proper one is for GLSL.

The "backend" suboption allows selecting the GUI backend used by vo_gl.
Normally, it's auto-selected, but sometimes it's desireable to explicitly
select it.
Remove the gl_sdl VO. This can now be done by using: --vo=gl:backend=sdl
This is based on svn commit 34438, and tries to be compatible with it. The
undocumented numeric backend names serve this purpose. (They are
undocumented because names are preferred.)

This is an experiment.
The change probably doesn't matter much.
One issue with the old code was that "large" images caused each sub-image
to be created and rendered as a new texture. "Large" in this case means
larger than 32x32 pixels, which actually isn't very large with screen
sizes beyond 1500x1000 pixels. This means rendering a simple subtitle for
a fullscreened video may allocate many small textures, one for each glyph.
On the other hand, the old code could be fixed by tuning the texture sizes
for "modern" work loads.
Also, the new code uses less deprecated OpenGL features and draws all
sub-images in one batch.
There are two possible issues the new code could cause:
- Drivers could have performance issues with the larger texture sizes and
the number of glTexSubImage2D calls on it
- There is only one EOSD texture, which could become full (it's enlarged
on demand, but restricted by driver texture size limitations)
It has been reported that this is faster on OSX with ATI GPUs than the old
code.

Currently there is no way to set the swap interval with a function
that has a signature compatible with other platforms' gl extensions.
Make a wrapper function around the gui toolkit method of setting the

Remove the useless dependency on MPGLContext from cocoa_common, since
it was used just to access the vo struct. Change gl_common to pass the
vo struct directly to all the cocoa_common functions.

This affects only the "new" VO API. The config() title argument was barely
used, and it's hardcoded to "MPlayer" in vf_vo.c. The X11 and the Cocoa
GUI backends, which are the only ones properly supporting window titles,
ignored this argument. Remove the title argument.
Add the vo_get_window_title function. All GUI VOs are supposed to use it
for the window title.

Add native Cocoa code to display an OpenGL window. Some of the code is
based on the OpenGL parts of vo_corevideo but I took the time to remove
old code based on Carbon.
There is autodetection in the configure script but you can use
--enable[disable]-cocoa to enable[disable] this.

The ARB shader code generated at the end of the shaders for scaling mode 4
and 5 was something like:
MAD yuv.g, b.r, {0.5}, a.r;
This appears to be semantically equivalent with:
MAD yuv.g, b.rrrr, {0.5, 0, 0, 0}, a.rrrr;
This has the consequence that the result register, yuv.g, will not contain
the value computed by the scale filter, but a.r. a.r is the unchanged
value sampled from the normal texture coordinates, so the filter did
effectively nothing and behaved as if cscale=0 was specified. The basic
mistake here is that yuv.g does not specify a single register, but it
specifies the full vector register yuv, with writing enabled on the g
channel. This means yuv.g will assigned the g channel of the the result
vector computed by the MAD instruction.

The GL_LUMINANCE16 texture format had only 8 bit precision on Mesa
based drivers. This caused heavy degradation of the image when playing
formats with more than 8 bits per pixel, such as 10 bit h264. Use
GL_R16 instead, which at least Mesa and Nvidia drivers actually
implement as 16 bit textures. Since sampling from this texture format
doesn't return anything meaningful in the other color components
(unlike luminance textures), the shader code has to be slightly
changed.
GL_R16 requires the GL_ARB_texture_rg extension. Check for it, and fall
back to the old texture format if it's not available.
The low precision of the GL_LUMINANCE16 format has just been fixed in
upstream Mesa, but it'll take a while before that fix is available in
distros.

The shader code was generated from very long strings with lots of
format specifiers with snprintf calls. It was almost impossible to
quickly tell what variables were inserted where in the shader. Make
this more readable by implementing a kind of simple variable
substitution, which allows replacing the format specifiers in the code
templates with with variable names.

The register combiner color conversion is broken and seems to use a
slightly incorrect color matrix (the image looks gray-ish). Completely
remove all code related to nVidia register combiners.
Unless you have an ancient nVidia GPU, there's no reason to prefer register
combiners over fragment shaders. Users with ancient GPUs without fragment
shader support can just use -vo xv.
Passing yuv=1 (register combiners) as sub option will print a warning and
use yuv=2 (fragment shaders) instead.
