I'm ditching this idea for now.
Here are my original notes on the scheme. cxpm.py has more information in the header comments on this experimental branch: https://github.com/schuylermartin45/seegol/blob/image_drawing_cxpm_v3/src/res/cxpm.py

New compression scheme: CXPM v3

One stream of bytes, 3 bytes per region
CWH to paint a region w/ C for W,H rectangle; region directions are sequential
0XY to indicate ul of next region
000 to terminate image
Old scheme "leaks" pixels occasionally for odd lengths(?)
