- debug: add provision for naming threads. allows adding current thread name to log messages and displays their names in the debugger. - replaced various if(err < 0) complain() sequences with new variants of CHECK_ERR (see lib.h) - fixes to mmgr/VC debug alloc enable code - improved h_mgr error reporting (now complains when h_free fails) - US -> UK english (partial) - fix tex_load double-free bug - move win32 mouse cursor code into sysdep - error dialog is now topmost to make sure it's visible (was a problem) - handle WM_QUIT before displaying error dialog (makes sure it's shown) also as in previous 3 revisions. This was SVN commit r2588.

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).
