There are a number of situations where alpha transparency of an object is not being rendered correctly - colors appear darker than they should be.

* PointSymbolizer: PNG files on a transparent background
* PointSymbolizer: TIF files of a transparent or opaque background
* RasterSymbolizer (GDAL): TIF files on a transparent or opaque background
* MarkerSymbolizer: (need to test for more details)

I have written a test case showing the problem with PNG PointSymbolizers and TIF RasterSymbolizers. Tested most recently with Trunk r2441 but have also noticed this issue in the 0.7.x branch.
