By dropping the unconditional logic op disable at the end of
rendering, this fixes GL errors being thrown in GLES2 contexts (which
don't have logic ops). On desktop, this also means a little less
overhead per draw call from taking one less trip through the
glEnable/glDisable switch statement of doom in Mesa.
The exchange here is that we end up taking a trip through it in the
XV, Render, and gradient-generation paths. If the glEnable() is
actually costly, we should probably cache our logic op state in our
screen, since there's no way the GL could make that switch statement
as cheap as the caller caching it would be.
v2: Don't forget to set the logic op in Xephyr's drawing.

When uploading bits to a texture which need reformatting to match a
supported GL format, a temporary buffer is allocated to hold the
reformatted bits. This gets freed in the general path, but is not
freed in the fast path because that includes an early return before
the call to free.
This patch removes the early return and places the general case under
an 'else' block, so that both paths reach the call to free.

Glamor has a mode where pixmaps will be constructed from numerous
small FBOs. This allows testing of the tiled pixmap code without
needing to create huge pixmaps.
However, the render glyph code assumed that it could create a pixmap
large enough for the glyph atlas. Instead of attempting to fix that
(which would be disruptive and not helpful), I've added a new pixmap
creation usage, GLAMOR_CREATE_NO_LARGE which forces allocation of a
single large FBO.
Now that we have pixmaps with varying FBO sizes, I then went around
and fixed the few places using the global FBO max size and replaced
that with the per-pixmap FBO tiling sizes, which were already present
in each large pixmap.
Xephyr has been changed to pass GLAMOR_CREATE_NO_LARGE when it creates
the screen pixmap as it doesn't want to deal with tiling either.

After the client has specified the contents of a mapped data store,

the mapping must be relinquished by calling

Our mappings were only getting reaped at PBO destroy time, after the
upload. If the GL implementation wasn't coherent, it would have used

may be attached to a fbo.

doesn't support link different objects which have cross
reference. Now we don't have that problem.
