cmd/gogio: add four colors to the e2e tests

Browse Source 
The e2e app now splits the window into four rectangles and paints them
differently.

The first advantage is that we now test that we see the entire Gio app.
Before, with a solid background color, we could be seeing a small part
of the window and we wouldn't tell the difference.

The second advantage is that we test more colors. In particular, the
fourth color includes a different alpha value, which renders the same on
JS and X11.
