Repo sample

Build ID: M20080221-1800

Steps To Reproduce:
[Repo sample soon to be attached.]

In Eclipse 3.3.2:

1. Import Repo.zip
2. Run as plugin
3. Window -> Show View -> Other -> Sample Category -> Repo View

Repeat in Eclipse 3.2.2 and compare the results.


More information:
Upon porting a plugin from Eclipse 3.2.2 to 3.3.2, I noticed that composite images (CompositeImageDescriptor) sometimes result in black backgrounds.

As the original plugin is far too large and complex to post, I have recreated a much smaller sample to reproduce with. (Please remember that the repo is very simplified just to show the behavior; the full plugin actually does use composite images in numerous places.)

The repo shows a non-composite, normal image in a label. Next it shows the same image run through a composite descriptor. Both display as expected.
Next, it shows a table. Column 0 shows the non-composite, normal image. Column 1 shows the same image run through a composite descriptor.

The results differ between Eclipse 3.2.2 and 3.3.2. In 3.2.2, in all cases the image is clear as is expected. In 3.3.2, column 1 results in a black image while the result display as expected. See (soon-to-be) attached images.

This may be a variation on bugs 168295 or 147072; however, both are marked fixed.

Environment: WinXP SP2 (Japanese), default (non-classic) style.
