clean up atlas api
...
We now bubble up an error if we ran out of texture space.
Previously we'd allocate a new texture but that wouldn't help anyone.
I've bumped up the texture size by default, too.
Longer term we should catch this, blow the font cache, cancel the
pending render and re-render.

Render cursor and selection for resized lines
...
If the user enlarges the terminal we can have regions of the vertex
buffer that have colors that default to alpha channel 0. This is
normally fine but breaks rendering of the cursor and the selection;
those attributes are out of band from the normal cell attributes,
especially for whitespace cells, so we need to handle those in
the degenerate case at the end of a line render.
Refactor the code that computes the cursor and selection colors
so that we can call it and use it in both places.

improve scroll_up perf
...
We were marking the entire scrollback history as dirty on each line
scroll. This was from the early days and isn't needed any more.
This brings the runtime of:
```
$ find /usr > /tmp/usr-files.txt
$ time cat /tmp/usr-files.txt
```
down from ~2.5s to ~1.2s.
Also avoid a redundant line_mut() call in set_cell().

Don't loop to read from pty
...
We don't need to be greedy in handling this read. It is important
not to for example when a lot of data is being written to the pty
we don't want that to starve the gui event handler and block sending
an interrupt signal.
