colors: store as doubles, rather than uint32_t
...
Since cairo uses doubles, we don't want to have to convert a uin32_t
to double values every time we render a cell.

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: let the render erase the scrolled up region
...
The grid scroll operation no longer inserts a DAMAGE_ERASE operation,
but instead manually clears the region. The render does the
corresponding thing.

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.

vt: wip: implement scrolling region
...
This is largely untested, but existing scrolling code has been
converted to using a terminal-global scrolling region that is defined
as start-end of the scrollable region.
This is compared to the old code where the scrolling region where
defined in terms of marginals, counted in lines from top and from
bottom.
