7a3eaad193 gl: Simplify glyph cache rendering 
We are currently using a weird mix of pango and cairo,
but there is no need for us to go through a pango
renderer here; we can just use cairo directly.

2c38b71ca5 glyph cache: Upload large glyphs in lookup () directly 
Instead of relying on a texture id of 0, which can happen for other
reasons, e.g. when the glyph is being scaled too small.

Fixes part of #2046

1c93bef0d5 glyph cache: check glyphs for scaled size 
We can't rely on just the ink_rect, since that might be without the
scaled applied, which is what ends up on the texture.

Fixes #2046

5f21c45f75 Revert "gl renderer: ops_set_modelview is (transfer full)" 
This reverts commit e904c49e8a.

This breaks HiDPI setups, i.e. setups where the call to
ops_set_modelview does not end up with a NULL transform.

259bbdcb09 Share glyph and icon caches 
Use the same texture atlases to back both
the glyph and icon caches, and unify their
sizes and management. Store big glyphs
in separate textures, so all atlases have
the same size. Tweak some of the eviction
parameters.

We share the caches across all GL contexts
on a display, unless the GSK_NO_SHARED_CACHES
env var is set.

3c6c07e94d gl: Avoid a memdup in glyph upload 
We don't need to dup the memory here if we
set up the image surface properly. This won't
matter for most glyphs, but some of them can
be big.

e0803f039f gl: Fix glyph cache aging 
The logic here seems faulty. We want to keep
a timestamp that tells us when the glyph was
last used, so always update the timestamp.

And whenever we use a glyph, it turns 'young'
again, so remove it from the old pixels
accounting.

The (MAX_AGE, MAX_AGE+CHECK_INTERVAL) interval
is only relevant to prevent us from turning
a cached glyph old more than once, and that
is already taken care of.
