7b0b3d9547 GskGLRenderer: Share programs between different renderers in same display 
This is similar to how we share texture atlases. Some added complexity
in that the program state also needed to be shared, so it had to move to
the shared Programs object.

With this change realization of additional GskRenderers when opening
popups went from ~60msec to ~35 msec on average.

1f0438e7fe gsk: Fix angle normalization 
I was getting assertions that normalize_angle() failed the
result < 260 check. Doing some research on this it turns out
to be a precision issue. If the incomming angle is very slightly
below zero, then adding 360 to it may end up with exactly 360.

I simplified the code a bit to avoid division and rounding, because in
practice most angles will be "just outside" the 0-360 degree anyway.
And i also added a workaround for the "result is 360" case by just
setting it to 0.

8fdb710c0f gl: Don't require too large texture for offsreen ops 
When rendering ops to an offscreen texture we take max-texture-size
in consideration and modify the scale we use such that the required
texture does not exceed the limit.

This means some rendering will be blocky/fuzzy, but that is better
than it being clipped.

7e8d8218b9 Revert "Break out cairo color matrix recoloring to gdk_cairo_image_surface_recolor()" 
We're not in the business of adding Cairo APIs. That's Cairo's job.

Also, we don't need this API anywhere like the original commit claimed,
so there's no need to make it available in any way.

This reverts commit afa6cc2369.
