gfx: extern "C"-ed wtime, util, win, wdbg_sym: minor / commenting only wdetect: don't skip gfx_card detect if buffer already filled glext_funcs: remove obsolete defs detect: call both OpenGL and platform-specific gfx_card detect; cleanup vendor name to remove copyright/Inc crap ogl: remove some variables that don't belong. moved vendor cleanup to detect. moved S3TC emu code to ogl_tex This was SVN commit r2905.

/*
|
|
|
|
FUNC is used for functions that are only extensions.
|
|
FUNC2 is used for functions that have been promoted to core features.
|
|
|
|
The FUNC2 call includes the version of OpenGL in which the extension was promoted,
|
|
and the pre- and post-promotion names (e.g. "glBindBufferARB" vs "glBindBuffer").
|
|
|
|
If the GL driver is advertising a sufficiently high version, we load the promoted
|
|
name; otherwise we use the *ARB name. (The spec says:
|
|
"GL implementations of such later revisions should continue to export the name
|
|
strings of promoted extensions in the EXTENSIONS string, and continue to support
|
|
the ARB-affixed versions of functions and enumerants as a transition aid."
|
|
but some drivers might be stupid/buggy and fail to do that, so we don't just use
|
|
the ARB names unconditionally.)
|
|
|
|
The names are made accessible to engine code only via the ARB name, to make it
|
|
obvious that care must be taken (i.e. by being certain that the extension is
|
|
actually supported).
