1037713 - (DrawAPIRefactor) imgIContainer::Draw API refactoring metabug

Status: RESOLVED FIXED

(Core :: Graphics: ImageLib, defect)

Description

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

This is a metabug to track all of the bugs related to the currently ongoing imgIContainer::Draw API refactoring.

The goal of the refactoring is three-fold:

1. Simplify the Draw API a bit.

2. Try to avoid some operations that decrease the numerical accuracy of the calculations we make when drawing. Numerical accuracy issues often result in user-visible rendering artifacts.

3. Allow callers to explicitly request an image to be drawn at a specific "source size". This will eventually be used for features like downsample-during-decode and proper multiresolution support for icons. It also so happens that it helps with goal #2.

Now that all of the dependencies have landed and stuck, this metabug can be marked fixed. Great success!
