380207 - canvas caches patterns so transforms don't work on patterns

Status: RESOLVED WORKSFORME

(Core :: Graphics: Canvas2D, defect, P3)

Description

[Hixie (not reading bugmail)]

STEPS TO REPRODUCE
 1. Create a pattern, use it for the fillStyle().
 2. FillRect() nothing.
 3. Translate.
 4. FillRect(). -> A
 5. Create a pattern, use it for the fillStyle().
 6. Translate.
 7. FillRect(). -> B

EXPECTED RESULTS
 A and B should look the same.

ACTUAL RESULTS
 Cairo caches the patterns so the translate is ignored.

(This is canvas doing the caching, not cairo itself.)

Unsure of the priority this should have. P2/P4?

This seems fixed with azure canvas.

Moving to p3 because no activity for at least 1 year(s).
