* Allow exactly one of these prefixes in header values:
0x, 0X, &h, &H. Note that "0x0xFFFFFF" is a correct value,
as the first 0x is consumed by the parser and the second by
the string-to-number conversion following strtol semantics.
* Allow arbitrary numbers of leading & and H
(and not h) in any order in override tag values.
* Reduce header values modulo 2**32 instead
of saturating them to LLONG_MIN/MAX.
* Saturate override tag values to INT32_MIN/MAX
rather than to LLONG_MIN/MAX.
* Don't fiddle with bytes in alpha override tag values.
(They can be outside of the 0..255 range.)
Also change the byte swapping code to be more sensible.
Fixes #80.
Fixes #145.
Fixes #178.
Also fixes our behavior in the case described in
https://code.google.com/p/xy-vsfilter/issues/detail?id=80.

Somewhat stolen from:
https://github.com/Cyberbeing/xy-VSFilter/blob/xy_sub_filter_rc3/src/subtitles/RTS.cpp#L2004
(xy-VSFilter started work on this in commit 014da6d9766417d7886eb867c9f2c14038f2a226)

Like VSFilter. '{' without a following '}' is just text, though
in vector drawing mode it still delimits individual drawings.
This also lets us nicely avoid '\0' hacks
in the \t override tag handler in parse_tag.

This adds 2 new API functions:
ass_set_selective_style_override()
ass_set_selective_style_override_enabled()
They can be used to force dialog text to use a specific ASS_Style. It
uses a fuzzy heuristic for that, and the quality of results may vary.
It does style overriding selectively and tries not to override things
that need explicit styling. The heuristic for that isn't set in stone
either, and can change with future libass versions.
Closes libass#88.

The parsing code allowed override tags after \p0 to affect the drawing.
This is incorrect. Finish the drawing object as soon as \p0 is
encountered instead.
This requires moving the code executing the style overrides from
get_next_char() in ass_parse.c to the main render loop in
ass_renderer.c, because we have to re-enter the rendering loop
inside of a tag. The old code was simply executing all tags until
a new character could be returned to the renderer loop, mutating up
the state (RenderContext fields) for the drawing after the drawing
was closed, but before it was rendered.
This fixes libass issue #47.

Make sure to update the border appropriately in the second pass, after
parsing.

Split up the combined event parsing and layout loop into two passes.
State information needed for layout are duplicated in GlyphInfo
structures.

Move the function apply_transition_effects, which parses event-global
effects and adjusts a few state variables, into ass_parse.c.

|
|
Move all code related to parsing event lines and processing override
tags into a separate file (ass_parse.c).
