vladislavbelov b1a89fbd89 Replaces UNICODE characters in the code by consistent ASCII characters. 
Beside consistency improves reading for such console tools like svn diff
or vim diff.

This was SVN commit r24625.

FUNC is used for functions that are only extensions.
FUNC2 is used for functions that have been promoted to core features.
FUNC3 is used for functions that have been promoted to core features
but have slightly changed semantics and need to be referred to by their
core name instead of extension name.
The FUNC2/FUNC3 calls include 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).
