8f6de1f955 gl renderer: Load flipped-y offscreen vertex data directly 
Instead of loading the unflipped version first and then flipping it.
Don't do it in add_render_ops either but only in the function actually
adding the render ops for the nodes, since those frequently have
early-out conditions that don't need the vertex data at all.

c5af463843 Cache glyph textures in render nodes 
This is a quick implementation that avoids many
glyph cache lookups. We keep an array of direct
pointers in the text render node, and throw those
cached pointers away whenever any atlases have
been dropped (since that may invalidate the cached
glyphs).

97f3371709 gl: avoid calculating vertex_data until necessary

7bff3abe8e glyph cache: Fix handling of big glyphs 
We were putting big glyphs in the cache, in their
own texture, but forgetting to mark the texture
as permanent, so it could be reused, leading to
occasional misrendering. Fix this by marking these
textures as permanent, and explicitly freeing them
when the cache entry gets old.

977ac2b31f gl: Do less work on glyph caching 
There is no need for us to be very precise about
aging the glyph entries. It is enough to check
occasionally and mark old entries. This reduces
the overhead of work we do every frame on the
caches, at the cost of letting glyphs linger
a bit longer in the cache.

528297f5e5 gl: avoid copying RenderOp to GArray 
Instead of copying the (rather large) RenderOp to the GArray, we can
simply set the fields directly in the allocated space for the struct.

is kept in tact across frame renderings.

b29feb193e gl: use memcmp to compare glyph cache keys 
We can just use memcmp here because even in the use of lookup keys with
C99 initializers, we can rely on any space between fields added by the

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.
