OpenGL with alpha blending.
Cocoa could do it as well, by drawing images with non-1.0 alpha.
The answer to your question is "yes, of course".
If you want to fade the whole screen, there are specific API's for
doing that in CoreGraphics framework. This is what games that use the
full screen usually do.

What frameworks and calls are involved with the fading trick that the
Screen Effects use when transitioning between pictures? Just the
fading transition, not the pan or zoom effect.
Also, is it possible to layer elements so that, lets say layer A at
the bottom of the stack fades out, layer B above layer A fades in, and
whatever graphic is in layer C is always on the top of the stack and
never fades out?
