Re: [PATCH] Allow low-cost reordering of view layers (for Gerber X2 sorting)

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.
