338545 - Canvas doesn't reset on resize

Status: RESOLVED FIXED

(Core :: Graphics: Canvas2D, defect)

Description

[Hixie (not reading bugmail)]

Resizing the canvas coordinate space (changing the height and width attributes) should reset the canvas bitmap to transparent black and the context to its initial state. Currently we don't reset the stroke colour.

r=mrbkap.

For posterity, I talked with vlad about the possibility of using any of these states before SetDimension is called, and he said that it wouldn't happen.
