Yes, but the delay is inperceptiable to humans.  On a 1200x900 24 bit
full scree copy, the delay will slow your framerate by a fraction at
best.

Here's the bottom line - we have an embedded system with finite storage,
and a security system that demands that we audit everything that goes in.
Including a seldom used module for applications that could otherwise
very easily use an API already built into the system and available today
would be a little over the top.
