* vo_opengl: fix a castwm42015-01-291-1/+1
| | | | Basically, the OpenGL API is crap (it takes an offset as pointer).
* vo_opengl: split out a helper for drawing primitiveswm42015-01-291-0/+21
| | | | | | | | Useful if we want to reduce the size of gl_video.c further. To some degree this emulates traditional glDrawArrays() usage. It also leaves a loophole for avoiding a reupload every time by leaving ptr==NULL, although this is unused for now.
* vo_opengl: some minor cleanupswm42015-01-291-0/+27
| | | | | | | | | | | | | | | default_tex_params() and texture_size() are each called only once, so move inline/reimplement them at the caller. image_dw/dh were unused. texture_w/h, image_format, and component_bits were rarely used, and can be replaced. Regroup some other fields. Rename surface_num to surface_idx, because the former sounded like a count, and not an index. Move fbosurface_next() closer to its callers too. Move the DebugMessageCallback() code to gl_utils.c (also simplify it by always setting the callback, instead of only when it changes).
* vo_opengl: move FBO helper to gl_utilswm42015-01-291-0/+77
| | | | | | | | | | | | | This is somewhat messy, because fbotex_init() itself was depending on some gl_video parameters unrelated to FBO creation (like what scaler was in use - what the fuck did this check do in this function?), so this commit does a bit more than moving code around. In particular, the FBO for the separate scaling intermediate step now always uses GL_NEAREST sampling, and all FBOs are destroyed/recreated on renderer reinitialization. This also moves the function matrix_ortho2d() - trivial enough not to put it into a separate commit.
* vo_opengl: create abstraction for VAOswm42015-01-281-0/+86
| | | | | | Handles stupid boilerplate OpenGL requires you to handle. It's the same code as in gl_video.c, although if no VAOs are available, the fallback code rebinds them on every draw call instead of just once.
* vo_opengl: move utility functions from loader to a separate filewm42015-01-281-0/+213
gl_common.c contained the function loader (which is big) and additional utility functions (not so big, but will grow when moving more out of gl_video.c). Just split them. There are no changes other than some modifications to comments.
