When compositing a no-reflect gradient, 'before' the gradient is empty,
but 'after' the gradient is padded with the final color. Both sides are
supposed to be empty.
This is fixed by moving the virtual stops to match the first and last
client-supplied stops for no-reflect gradients, then causing everything
'before' the initial virtual stop and 'after' the final virtual stop to
emit rgba(0,0,0,0). This does not impact gradients using the other
reflect modes.

If _pt_distance is negative, it causes the final distance to be negative

avoids this problem, and simplifies some equations as a bonus.

glamor_compute_transform_clipped_regions() uses a temporary box32

thus causing a potential overflow.
If an overflow occurs, the given region is invalid and the pixmap
init region will fail.
Simply check that the coordinates won't overflow when copying back to
the box16, avoiding a crash later down the line in glamor.

Fixes subtle breakage which could sometimes trigger after a server reset
with multiple screens using glamor:
Screen A enters glamor_close_screen last and calls various cleanup
functions, which at some point call glamor_make_current to make sure
screen A's GL context is current. This sets lastGLContext to screen A's
&glamor_priv->ctx. Finally, glamor_close_screen calls
glamor_release_screen_priv, which calls free(glamor_priv).
Later, screen B enters glamor_init, which allocates a new glamor_priv.
With bad luck, this can return the same pointer which was previously
used for screen A's glamor_priv. So when screen B's glamor_init calls
glamor_make_current, lastGLContext == &glamor_priv->ctx, so MakeCurrent
isn't called for screen B's GL context, and the following OpenGL API
calls triggered by glamor_init mess up screen A's GL context.
The observed end result of this was a crash in glamor_get_vbo_space
because glamor_priv->vbo didn't match the GL context, though there might
be other possible outcomes.
Assigning the actual GL context pointer to lastGLContext prevents this
by preventing the false negative test in glamor_make_current.
