render: revert glyph caching
...
Instead, try to group as long sequences of glyphs as possible, as
fewer calls to cairo_show_glyphs() is *much* faster.

render: draw pre-rendered glyph OVER background

This allows us to render the background dynamically. Note that
pre-rendered glyphs still have wrong foreground color.

render: cache glyph masks
...
Cache rendered glyph masks for each font combo. When rendering text,
use these when possible (standard ASCII).
For now, use the cached glyph as a mask. This allows colors to just
work. It would be faster to cache a completely pre-rendered image, but
then we would need one image for each background/foreground combo.

grid: attributes now track whether we've set a foreground/background color
...
This means we don't have to explicitly set the foreground/background
to the grid's default colors whenever we reset/clear a cell, and we
can instead simply memset() the entire cell to 0.
This also means the renderer has to get the default color when
rendering a cell without a foreground/background color set.

scroll-region: don't clear damage queue when changing scroll region
...
Vim, for example, changes the scroll region every time you scroll a
single line. Thus, resetting the damage queue is slow.
This reworks the damage handling of scroll updates:
* Split damage queue into two: one for scroll operations and one for
update/erase operations.
* Don't separate update/erase operations inside/outside the scroll
region
* Store the current scroll region in the scroll damage operation. This
allows us to stack multiple scroll operations with different scroll
regions.
* When updating update/erase operations after a scroll operation,
split the update/erase operations if necessary (the current scroll
operation may have a scroll region different from before, thus
forcing us to split existing update/erase operations.
* The renderer no longer erases after a scroll. The scroll operation
also adds an erase operation. This also means that erase operation
are subject to adjustments by later scroll operations.
