Details

(Whiteboard: [gfx-noted]) 

As part of Moz2Dification we want to replace gfxPoint with gfx::Point. The former uses double-precision floats, the latter uses single-precision floats.

As a first step I tried changing gfxPoint to use single-precision floats. The try run results had lots of reftest failures, unfortunately.

(A second, Windows-only run was needed because the first run had a Windows-only compile error.)

A similar problem is blocking the removal of gfxSize in bug 1216396, but for gfxPoint there are more failures.

I'm unsure how to proceed from here.
