Hi list,

gallium-st-api has come to the point that st/glx passes as many piglit
quick tests as st/glx in master does.  I'd like to merge it to master
some time this week.

gallium-st-api implements a new interface, st_api.h, that aims to be a
replacement for st_public.h.  The new interface paves the way to
implement various EGL specific features.  Meanwhile, it is hopefully
st_public.h done right.  pipe_screen::flush_frontbuffer, which needs a
pipe_screen-specific winsys drawable handle, is no longer called
directly by st/mesa.  pipe_screen::update_buffer is no longer needed,
and the validation of drawables is done only when the drawable has
changed (resized or buffers swapped).

st_api.h can coexist with st_public.h.  It has been implemented by both
st/mesa and st/vega.  Co state trackers, however, can only choose to use
one of the interfaces.  st/glx and st/egl have been converted to use
st_api.h.  The plan is to convert st/dri and st/wgl to st_api.h after
the merge, and then drop st_public.h support.  Work on EGLImage
extensions will start also after the merge.

Let me know if there is any concern.
