Parsing the texture data as raw strings makes the textures the most
portable and self-contained. In order to facilitate different types of
shaders, the parse_user_shader interaction has been changed to instead
have it loop through blocks and call the passed functions for each valid
block parsed. This is more modular and also cleaner, with better code
separation.
Closes#4586.
Was started by Uoti Urpala in commit 5f631d1c. Although it was made part
of demux_mkv.c, it's quite obvious that it's not based on any
pre-existing demux_mkv.c code (or ebml.c/.h for that matter). Anyone
else who has touched this code every since has already agreed to LGPL
relicensing.
This replaces the previous TRANSFORM by WIDTH, HEIGHT and OFFSET where
WIDTH and HEIGHT are RPN expressions. This allows for more fine-grained
control over the output size, and also makes sure that overwriting
existing textures works more cleanly.
(Also add some more useful bstr functions)
BSTR_P() passes the string length and start pointer to printf-like
functions. If the lenfth is 0, the pointer can be NULL, but we're
actually still not allowed to pass a NULL pointer in any case.
This is mostly a technically, because nobody in their right mind would
attempt to specifically break such cases. But it's still undefined
behavior, and some libcs might be strict about this.
bstr.c doesn't really deserve its own directory, and compat had just
a few files, most of which may as well be in osdep. There isn't really
any justification for these extra directories, so get rid of them.
The compat/libav.h was empty - just delete it. We changed our approach
to API compatibility, and will likely not need it anymore.
