 Bugs:
 
-* Glyph baseline is using the main font, but it can vary font to font
-
 Performance:
 
-* libuv allocates on every read, we should use a read buffer pool
 * for scrollback, investigate using segmented list for sufficiently large
   scrollback scenarios.
 * reflow: text reflow is really poorly implemented right now specifically
   for shrinking columns. Look into this. This may require changing the
   screen data structure.
-* Screen cell structure should be rethought to use some data oriented design,
-  also bring it closer to GPU cells, perhaps.
 * Loading fonts on startups should probably happen in multiple threads
+* Windowing event loop should not check `shouldClose` on every window
+  and should use should close callbacks instead.
+* Window shutdown should be done in threads but GLFW window close cannot
+  be done in multiple threads making this a bit tricky.

   - need fallback glyphs if they're not supported
   - can effect a crash using `vttest` menu `3 10` since it tries to parse
     ASCII as UTF-8.
-* Graphemes need to be detected and treated as a single unit
