Of course glXGetVideoSyncSGI doesn't return the swap interval. The feature
only exists in the Mesa extension... which is the whole reason I created the
Mesa extension! Note that the Mesa extension allows drivers to default to a
swap interval of 0. If the Mesa extension exists, use its value. Only
consider the SGI extension when the Mesa extension is not available.
Fixes bug #22604.
Tries to use either GLX_MESA_swap_control or GLX_SGI_video_sync to
detect whether the display is synchronized to the vertical blank. If
it detects this, a message will be printed. HOPEFULLY this will
prevent some of the bug reports such as "glxgears only gets 59.7fps.
What's wrong with my driver?"
Instead of passing in a fixed struct, the loader now passes in a list
of __DRIextension structs, to advertise the functionality it can provide
to the driver. Each extension is individually versioned and can be
extended or phased out as the interface develops.
Add compile support in the xdemos directory for OpenVMS
