I really want/need/am in love with V2+i's tranlucency functions, but I prefer v2.7's other features and non-suckitude, so I was wondering if all (or any) of V2+i's translucency functions are planned for 2.7? And if not, can I request them?
Alpha is nice, but just way too static for 90% of what I want to do.

P.S.
Are Rotscale and Wrapblit comming back too?

Image tinting will be implemented. You'll be able to blit an image and mix the whole of it with a single colour. (alpha channels will be mixed too)
Colour subtraction will probably have to go. From what I've heard, very few cards can support it. Colour addition is more widespread, so we'll see.
Yes, both RotScale and WrapBlit are planned. (and both are pretty simple with OpenGL)

I'm becoming more and more disapointed with PC technology... It never seems to do any of the cool stuff... No wonder the consoles look ten times better.
What about a function that achives color subtraction by reading the pixel values from the area being blitted to, subtracting the values from the blit itself, and then just directly blitting the modified image with no translucency, since the values have been pre-calculated as it were? Is that possible, or is it impossible to read from an unfinished frame?
Otherwise, image tinting sounds cool, and Rotscale and Wrapblit are two of my favorites.
Thanks for the speedy reply. :)

Of course it's possible! ^_^ The question is whether or not it'll be fast enough to be useful. Any time you have to resort to software, it's bound to be slow. I'd be much happier if all the work was done by the graphics card.
You can attain the same effect with a black image, and tweaking the alpha channel to get various levels of blackness, by the way. :)

Although I know a bit ASM I have no clue when it comes to MMX/SSE/3Dnow etc.
BTW, I believe that most (!) effects achieveable with add/sub can be attained with alpha and some use of the channel copying function.
