We do have hardware on Tegra that doesn't support RGBA cursors and if at all possible I'd very much like to support that as well. New generations can do RGBA but still support the old pixel format. Having the option of supporting all formats would be nice. There was some discussion about implementing a bunch of plane properties so I think having one to enumerate a set of pixel formats wouldn't be such a big deal. Thierry
