[chromium] WebGL texImage2D fails with deferred image decoding

Summary [chromium] WebGL texImage2D fails with deferred image decoding
Hin-Chung Lam
Reported 2012-11-14 17:59:25 PST
When deferred image decoding is enabled WebGL's texImage2D using an Image object will fail. This is due to the fact that it generates an ImageFrame marked as incomplete which WebGL rejects.

Seems fairly reasonable to me, but I think Ken or Stephen are more familiar with this bit.

I talked to Dirk about this. Since I want to run this test with --enable-deferred-image-decoding virtual suite there's a couple options: 1. Add a virtual suite that runs *one* test in fast/canvas/webgl 2. Copy the test from fast/canvas/webgl 3. Write a simple webgl test in fast/images that does exactly what I need I did just 3.

Comment on attachment 174307 [details] Patch Looks good. Please make sure the WebGL conformance suite and the fast/canvas/webgl/ layout tests pass with --enable-deferred-image-decoding, as there are many other tests which already exercise this path, some potentially more strenuously. r=me

This results incompelte -> incomplete
