/* The GLX API dispatcher (i.e. this code) is being built into stand-alone
35
* Mesa. We don't know anything about XFree86 or real GLX so we define a
36
* minimal __GLXContextRec here so some of the functions in this file can
39
typedef struct __GLXcontextRec {
42
GLXDrawable currentDrawable;
43
GLXDrawable currentReadable;
49
* Almost all the GLX API functions get routed through this dispatch table.
50
* The exceptions are the glXGetCurrentXXX() functions.
52
* This dispatch table allows multiple GLX client-side modules to coexist.
53
* Specifically, a real GLX library (like SGI's or the Utah GLX) and Mesa's
54
* pseudo-GLX can be present at the same time. The former being used on
55
* GLX-enabled X servers and the later on non-GLX X servers.
57
* Red Hat has been using this since Red Hat Linux 7.0 (I think).
58
* This'll be a standard feature in XFree86 4.3. It basically allows one
59
* libGL to do both DRI-rendering and "fake GLX" rendering to X displays
60
* that lack the GLX extension.
