2bf34fe8d9 glamor: Pass depth to glamor_pm_is_solid and glamor_set_planemask
Instead of passing the destination drawable, just pass the depth, as
the underlying functions need only that to check whether the planemask
is going to work.

This API change will allow higher level functions to not need the
destination pixmap.

9e9fcf5780 glamor: Add a helper function for the common GL_QUADS fallback pattern.
We should do better than this with an index buffer, but for now at
least make it so that we don't have to copy the same code to new
places.

6ba6cc57e1 glamor: Just set the logic op to what we want at the start of all rendering.
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.

The latter might not be available on GLES2.

2ab0fba9df glamor: Drop unnecessary glTexParameteri() in SetSpans().
If this path needed the filters set, so would all the other
glDrawArrays() callers.  But they don't.

fab0a4a4c9 glamor: Replace glamor_get/put_context() with just glamor_make_current().
Now that we have the DIX global state for the current context, we
don't need to track nesting to try to reduce MakeCurrent overhead.

v2: Fix a mistaken replacement of a put_context with make_current in
    glamor_fill_spans_gl() (caught by keithp).

0a6d311618 glamor: Add glamor_program based fill/set/get spans
This accelerates spans operations using GPU-based geometry computation

-wellipse500 goes from about 4k/sec before the patch, to ~8k/sec in
the GLES2 fallback loop, to ~100k/sec in desktop mode.

v2: Rebase on skipping the prepare rewrite for now, and fix the GLSL
    1.20 and GLES2 cases (changes by anholt).
