Color especial effects

I've spent the past few days working on 2D related stuff and minor fixes. Quite a few hours have been invested "only" logging and debugging some demos still not working properly, because, for example, some basic stuff seems to be still failing. Also, I've worked a bit onto getting more speed from 3D, which got a bit faster, but still needs quite a lot of work.

Today I'll talk a bit about the last one I've been working on, even if the actual implementation is more a raft from what it should be. I'm talking about the pixel blending, which can be used, for example, to cross fade from one image to another (as used in Zelda Gallery), or blending multiple images (for example, I think that's what it's used for "MP: First Hunt" menus). You can get a proper reference here. I've still to make some proper improvements, because I still don't support some effects that can be achieved with multiple source selections, for example, but I'll fix them in a few days.

Today I prefered to leave the technical details aside, as I don't really still feel confident about how the special color effects work. Anyway, here's the blend support as seen in Zelda Gallery (source, half blended, and destiny):

And that's all, have fun :)
