Benjamin Woodruff 3971fc9b4e Save and restore the ctx for cached characters 
Drawing dim colors sets the globalAlpha to 0.5, so we need to
save/restore the ctx state. Otherwise, every time we draw some dim
content, our display will get progressively dimmer.

I tested this by running `echo '\u001b[2mfoo'` a few times in zsh.

Fixes #1424

Benjamin Woodruff a5a03c40f2 Batch background draws together to reduce draws 
Adjacent cells on the same row sharing the same background color will be
drawn using the same `fillCells` call. This should make drawing an
application with a solid or mostly solid background color (e.g. vim)
faster.

I set vim to draw the background color for a file, and started scrolling
through it. Before, _drawBackground was taking around 6ms per frame.
After this commit, it was taking around 0.5ms per frame.

Based on prior experience, I'd expect these results to be more drastic
for larger terminal windows. The demo's window is pretty small.

Benjamin Woodruff b853aa4929 Separate foreground & background rendering passes 
I'm primarily interested in doing this because it'll allow me to
optimize the background rendering in later diffs, but this may also make
it possible to fix some minor rendering issues.

Right now, if we draw a single-width character that overflows its cell's
bounds, and the character to the right of it has a background, that
background may cover up the first character's foreground. By drawing the
background in a separate pass, we can avoid those cases.

There's still some issues with how dirty regions are computed that makes
rendering stuff like that flaky, but this at least gets us closer to
"correct" rendering.

Other terminal emulators (e.g. alacritty) render the foreground and
background in separate passes:
