The core of this change is in gfxContext.*: - change gfxContext::CurrentMatrix() and gfxContext::SetMatrix() to return and take a Matrix respectively, instead of converting to and from a gfxMatrix (which uses doubles). These functions therefore will now match the native representation of the transform in gfxContext. - add two new functions CurrentMatrixDouble() and SetMatrixDouble() that do what the old CurrentMatrix() and SetMatrix() used to do, i.e. convert between the float matrix and the double matrix. The rest of the change is just updating the call sites to avoid round- tripping between floats and doubles where possible. Call sites that are hard to fix are migrated to the new XXXDouble functions which preserves the existing behaviour. MozReview-Commit-ID: 5sbBpLUus3U
