egl: Initialize display resources with their display.
Change _eglInitSurface, _eglInitContext, and _eglInitImage to take an
_EGLDisplay instead of an _EGLDriver. This is a more natural form, and
plus, the display encodes information such as the extensions supported
that might be required for attribute list parsing.
They are either unit tests or to demonstrate how functions are supposed
to be used. The unit test is outdated and it should be better to take a
look at any of the working drivers to see how a function is used.
if independent blend state was disabled, only the data from first rt was
stored, however the comparison used the full state, hence there never was
a match and always a new object was created.
Fixes a huge performance drop with llvmpipe due to recompilation.
Commit 2708ddfb06 caused a few regressions.
We need to check/validate state after calling bind_arrays() because
it might set the _NEW_ARRAYS flag if the varying VP inputs change.
The symptom of this problem was some attribute arrays being ignored
(or interpreted as constant-valued) in glDrawRangeElements or
glMultiDrawElements.
A follow-on patch will add some additional asserts to try to catch
this kind of thing in the future.

mesa: do state validation in _mesa_valid_to_render()
...rather than checking/validating before all the calls to
_mesa_valid_to_render() and valid_to_render().
The next patch will actually fix some bugs...
(cherry picked from commit 23eda89ec8)
mesa: Warn when indices are out of bounds, but do not skip the draw in debug builds.
The driver (or preferably the hardware) should handle out of bounds
indices.
If there are problems then it's better to detect those in the debug
builds.

softpipe: support all TGSI fragment coord conventions (v4)
Changes in v4:
- Rebase and modify for changes in previous patches
Changes in v3:
- Use positive caps instead of negative caps
Changes in v2:
- Now takes the fragment convention directly from the fragment shader
Adds internal support for all fragment coord conventions to softpipe.
This patch is not required for use with the current state trackers, but it
allows softpipe to run any TGSI program and enhances performance.
st/mesa: Gallium support for ARB_fragment_coord_conventions (v4)
Changes in v4;
- Implemented Brian Paul's style suggestions
Changes in v3:
- Use positive caps instead of negative ones
Changes in v2:
- Updated formatting
The state tracker will use the TGSI convention properties if the hardware
exposes the appropriate capability, and otherwise adjust WPOS itself.
This will also fix some drivers that were previously broken due to their
incorrect, inadvertent, use of conventions other than upper_left+half_integer.
