GL 3.0 (EXT_draw_buffers2) and other APIs allow independent blend enables and
write masks per render target, ARB_draw_buffers_blend (and other APIs) also
allow independent blend functions. Things like dithering, logic ops however
are not extended to be per rendertarget, that might be conceptually possible
however it doesn't look like any API wants to expose this.
The functions can be used to check if a display is supported without
creating a struct native_display. It uses a probe object that can be
shared across drivers.
In current design, multiple drivers will probe the same display and the
best driver is determined. The cache can be used by the drivers to
store and share the probed data.
It can be used to load the user driver specified by EGL_DRIVER, or a set
of drivers specified by EGL_DISPLAY, or the default driver, and in that
order.
Change ar flag from -v (-verbose) to -c (silence console output)
so that it stops causing make_ar_static_lib() to return a bunch
of output other than the resulting library file.

The pull constants require sending out to an overworked shared unit
and waiting for a response, while push constants are nicely loaded in
for us at thread dispatch time. By putting things we access in every
VS invocation there, ETQW performance improved by 2.5% +/- 1.6% (n=6).
Previously for frame throttling we would wait on the first batch after
a swap before emitting another swap, because we had no hook after a
swap was emitted. This meant that if an app managed to squeeze
everything it for a frame had into one batch, it would lock-step with
the GPU. With the swapbuffers changes, we now have the entrypoint we
want.
This takes the WoW intro screen from 25% GPU idle and visibly jerky to
4-5% GPU idle and rather smooth. Other apps such as OpenArena have
run into this problem as well.
Sun cc 5.9 and later (__SUNPRO_C >= 0x590) support __attribute__ calls
for aligned, always_inline, noinline, pure, const, and malloc.
This commit includes updates to files that were regenerated by gl_XML.py
after adding the __SUNPRO_C checks to it
