1254360 - Stop accessing the imgIContainer's width and height in nsDisplayImage::ConfigureLayer and related methods

Status: RESOLVED INVALID

(Core :: Graphics: ImageLib, task, P3)

Description

[Seth Fowler [:seth] [:s2h]]

In bug 1251804 we updated nsDisplayImage::ConfigureLayer (and the related ConfigureLayer() methods from other image-related display list items) to scale the layer's transform based on the ImageContainer being used, rather than on the imgIContainer's size. However, to avoid changing error-handling behavior, we continued to check that the imgIContainer's width and height were available.

In this followup, let's remove that check, since it should not be necessary. (And it adds a substantial number of lines of code.)
