These functions are the API of Gallium state tracker, and are used by
EGL.

This commit adds functions to bind a pipe surface to a texture. This
allows texturing directly from the surface.

Prevents segmentation fault when trying to set the viewport/scissor
after a context/drawable visual mismatch.
|
|
The pointers to the front/back renderbuffers are exchanged.
This new function isn't actually used yet...

This allows the winsys to explicitly specify gallium surfaces for a
framebuffer object.

The cell driver still uses an internal CELL_FLUSH_WAIT flag, in the long run
proper fencing should be implemented for it.

These are changes that are in our internal branch, but somehow were skipped
so far. It was done using visual comparison of the branches --
it is likely that changes are being carried on the wrong way

If an app never called glViewport, the viewport size was always 0 by 0 pixels.
Now pass initial size to st_create_framebuffer() and initialize the viewport
and scissor bounds in st_make_current().
This could also be fixed by ensuring the gl_framebuffers passed to
_mesa_make_current() were initialized to the right size. But that involves
allocating the renderbuffers/pipe_surfaces earlier and that runs into some
other issues ATM.
Also remove obsolete createRenderbuffers param to st_create_framebuffer().

st_create_framebuffer() now takes pipe_formats for the color, depth, stencil
buffers.
This avoids a round-about chain of calls to pipe->is_format_supported() for
window renderbuffers (their format never changes).
Renderbuffer format selection code in st_format.c is simpler now too.

The state tracker doesn't have to directly call winsys->wait_idle() anymore.
glFlush and glFinish both go through pipe->flush() now.

XMesaContext has an st_context * which contains a mesa context.

Some git wierdness going on.

softpipe/state_tracker --> state_tracker/
softpipe/ --> pipe/
softpipe/generic --> pipe/softpipe/
I don't think pipe is a great name, but I disliked all the others too.
Luckily it's fairly easy to rename with git, so this can be revisited
later.
