Thats happening but will take time both to do and for the results to
filter through to the masses.

If my compile is generating 60 screens a second yes. Or at least I need
it not to slow the compile.

A lot of older PC video hardware cannot do alpha blend. This has a very
brutal performance impact - and is one reason that turning alpha off
works so well. A lot of Xorg drivers don't support blending, and many
cannot handle blending for large offscreen objects.
