Rename some arguments, since atlases->atlases is awful.

e961943508 Fix a refcounting mishap 
We were missing a ref, causing caches to go missing
when a window is opened twice.

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.

There was a TODO here to avoid iterating the

actually log the number of glyphs that was dropped.

3f1afd6040 gl glyphcache: Don't choke on huge glyphs 
We blindly assume everywhere that a single glyph will definitely fit on
one atlas, but that's not always the case.
For now, don't crash or produce GL errors.

aa922f0779 gl renderer: Pass correct matrix category when rendering offscreen 
We can't just pretend we have an identity matrix when we are actually
scaling. This fixes the node editor sometimes not drawing things when
rendering to a texture. We were mistakenly discaring render nodes
because the bounds transformation was wrong.

63267a2f70 gl renderer: Render fallback nodes upside down 
We stuff both gl-drawn and cairo-drawn textures into the same cache, so
we can't really assume that we need to draw any of them flipped or not.
Fix this by drawing fallback stuff upside down and then using
upside-down vertex data for everything.
