This optimization will take more work, and we already got a lot of the
way there by optimizing how we send data down to the GPU.

Only reallocate the GPU buffer if our CPU capacity changes
...
Previously, every single render was re-allocating a fairly large (~1MB)
buffer on the GPU. The recommended best practice is to allocate once and
then use `glBufferSubData` to update the memory in-place on the GPU.
We now track the last size we sent to the GPU, compare it to our copy on
the CPU, and if it _grows_ then we reallocate the GPU buffer. If it
shrinks we leave the GPU as-is for now. After this, we use the sub-data
routines to update the data in place.

fix ttyWrite calculation to avoid truncating data

the math was wrong. The easiest way to see this was attempting to paste

enable retina on Mac, set OpenGL to pixel size properly
...
This makes things look a bit better, but trades pixelation for blurry
(still TODO). This also fixes an issue on Retina where if you resize
it'd make the viewport 1/4 of the size. The issue here is that OpenGL
uses pixels and glfw uses screen coordinates for everything. We adapt
the screen coords to pixels properly here.

Merge branch 'reflow'
...
This actually doesn't implement reflow but I wanted to merge this
because it has an important refactor and clarity around screen
operations.
It is now clearly defined in the API what portion of the screen you're
accessing (active, viewport, etc.) and the terminal only operates on the
active area (fixing TODO item in diff).
This is all groundwork I found was necessary to even start thinking
about reflow.
