60e89f6328 Fix latency issue with clipboard/selection handling 
We now use mio to select on both the xcb connection and the
channel that we're using to bridge the threads.

No real functional changes, this is just moving some things
around to make it a bit easier to address the laggy selection
handling.

981d939298 More gracefully handle running out of texture space 
I manually checked this by setting TEX_SIZE to a small value

4092796db3 Fix an issue where the background color rendered gray instead of black 
When using the default monospace font on ubuntu (typicaly
DejaVuSansMono), the texture atlas would end up the bottom left pixel
being a shade of gray.

Since we were using (0,0) coords for whitespace cells, all whitespace
cells would appear shaded gray.

We now reserve a black pixel in the bottom left of the underline texture
and switch to that for whitespace instead.

I added Debug support to the ColorPalette while tracking this down,
and figured that I might as well keep it.

79ebf717e8 provide a more targeted channel for wakeups 
This allows using the mio poll timer as the signal for drawing

9da069e1e9 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.

279b2018fd 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.
