[PATCH 1/3] [v3] gdiplus/tests: Add more PNG color format tests.

[Akihiro Sagawa]

In v3,
 - win_skip tests if broken gdiplus is used.
 - Remove ugly broken() conditions.
 - Use a private chunk name instead of standard chunk name.

Thanks for Vincent's review and comments.

In v2,
 - Fix test failures on broken XP, Vista, 2003.
 - Fix the expected value for 1bpp gray scale image with tRNS chunk.
 - Introduce color_space_mask to test other color space flags aren't set.
