Visualize the way gvim draws text

The script 'vis.py' loads a log of drawing calls from a file called draw.log (produced by running 'gvim -f > draw.log' after applying vim.patch and rebuilding). It lets you single-step through them using <Left>/<Right> keys. Use 'q' to quit.

The last draw call is highlighted in blue.

This gist contains a snapshot of draw calls produced by running gvim, typing :help, then pressing <PageDown> to scroll one page and finally quitting with :qa.

(I'm debugging a redraw problem with an experimental GTK+ 3 patch.)

Here's a screencast of the script in motion: https://asciinema.org/a/35507
