egl: Restore "bogus" DRI2 invalidate event code.
I had removed it in commit
1e7776ca2bc59a6978d9b933d23852d47078dfa8
because it was obviously wrong -- why do we care whether the server is a
version that emits events, if we're not watching for the server's events,
anyway? And why would you only invalidate on a server that emits
invalidate events, when the comment said to emit invalidates if the server
*doesn't*? Only, I missed that we otherwise don't flag that our buffers
might have changed at swap time at all, so the driver was only checking
for new buffers when triggered by the Viewport hack. Of course you don't
expect Viewport to be called after a swap.
So, this is effectively a revert of the previous commit, except that I
dropped the check for only emitting invalidates on a new server -- we
*always* need to invalidate if we're doing a SwapBuffers.

glsl: Remove shader stage checking for extension handling.
Certain extensions only add functionality to particular shader stages.
(For example, ARB_draw_instanced only adds variables to the vertex
shader stage.)
Previously, we only allowed such extensions to be enabled in the shader
stages where they're useful. However, I've never found any text which
mandates that behavior; in my opinion, you should be able to turn on
extensions in any shader stage, even if they have no effect.

which suggests round to next finite value but round-to-zero would also
be allowed, but finite values must not be flushed to infinity in either

Hence I believe it makes sense to do the same for half-floats too.
We could probably also use round-to-zero consistently, which is in fact
required by d3d10 (but it doesn't seem to matter much).
Does not match the mesa core function doing the same though (which is
saying it was built to match intel gpus which I don't believe for a

The linker matches up variables in interface blocks according to their

example, in a block like this:

This is unnecessary, and leads to problems in supporting geometry
