These minor changes allow getprocaddress to return an error code
in the case of test failure. This allows the program to be integrated
into the piglit test suite.
- Allow the getprocaddress test to test extensions not supported by
Mesa. The original getprocaddress.py script only included OpenGL
extension functions that were in Mesa dispatch tables. Now all
known extension functions (as detailed in gl_API.xml) are included.
As the test does not link against any extension function symbols
(i.e. it uses glXGetProcAddress() for all extension functions),
it still compiles and links against Mesa; but now the same
binary can be used to test extensions not yet supported by Mesa.
- Extend the list of tested extension functions. The last revision
of this test exercised 16 extension functions; this revision adds
support for 95 more.
Create one window and render into it with two GLX contexts. Setup the
rendering state differently for each context to be sure there's no state
"bleeding" between contexts.
This is a simple demo for eglBindTexImage. It uses a OpenGL context,
instead of the required OpenGL ES one. But it still suffices the demo
and test purpose.

use glCompressedTexSubImage2DARB also with xoffset by splitting into 3 calls
in total. Dunno if the top/bottom reversal is intentional but leave as is.
This fixes the problem that first frame would report bogus usage values.
Problem was caused because get_frame_usage returned data from previous buffer
swap.

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.

Pull in a minimal version of statechange shortcircuiting in display
list compilation. This affects only glMaterial and glShadeModel state,
and includes quite a few tests to exercise various tricky cases.
If this goes well, will consider extending to all state in the future.
Where vbo save nodes are terminated with a call to DO_FALLBACK(), as in
the case of a recursive CallList which is itself within a Begin/End pair,
there two problems:
1) The display list node's primitive information was incorrect, stating
the cut-off prim had zero vertices
2) On replay, we would get confused by a primitive that started in a
node, but was terminated by individual opcodes.
This change fixes the first problem by correctly terminating the last
primitive on fallback, and the second by forcing the display list to
use the Loopback path, converting all nodes into immediate-mode rendering.
The loopback fix is a performance hit, but avoiding this would require
a fairly large rework of this code.
State-change functions which precede the first call to glEnd() in
a compiled list are vulnerable to not being executed when that list
is called.
In particular this can happen if a list is invoked from within a
begin/end pair, as in this example.
When one display list calls another display list, it is possible
that the calling display list makes state-changes or other actions which
invalidate any attempt at caching or state-change elimination in the
calling list.
This test exercises one such case, where the called list consists of just
a single glShadeModel() call.
