I've copied the VGA approach here, with the pixel generator hard-coded. The usage here is slightly different:

Looks good, but:
- please update for the applet to build,
- please add dual newlines before/after any class or function at the toplevel,
- please add yourself as a code owner for it.

This patch implements a basic test pattern generator for HUB75 LED Matrix panels, much like the VGA output applet.
The output is only 3-bit / 8-color, with no attempt at producing more colors or brightness control.
Panels of various shapes and sizes are supported, I've developed with a 64x64 1/32 scan panel, and have also tested with a second connected to produce a resolution of 128x64.
