Hi Jon,

I tested the patch on W7 -32 bits.

Unfortunately, it does not work as expected:

I loaded 2 Gerber files and switch from Cairo to OpenGL (reorder X2 command gives similar results):
current version (without patch): calculation time 12 to 15 seconds
with patch: calculation time about 2 minutes.
