1034528 - Get rid of the propagating creators of Thebes backed gfxContexts

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Jonathan Watt [:jwatt]]

We have a few instances of code creating temporary Thebes backed gfxContexts if another gfxContext (either passed in or previously stored) is a Thebes backed gfxContext. This code can only be reached if other code creates Thebes backed gfxContexts, and since I've killed all such other code these propagating instances are now dead code.
