From 0ab5ce151c4507966c135ab3986cf2b28b36d6c6 Mon Sep 17 00:00:00 2001 From: Herb Derby Date: Mon, 30 Jul 2018 10:10:40 -0400 Subject: Move path leaf loop to drawer This CL makes GPU and Raster use the same path drawing interface. When I get the main body of regenerate over into the glyph run system, I I can refactor a lot of annoyingly similar code away.
