What is the fastest way to clear the zbuffer and backgroundcolor in the
following scenario:

1 pipe with 2 attached channels for stereo display (1 CPU).

Timeing my application i found that using

 pfClearChan
 pfClear

is slow.

Things i want to do are :

clear the whole screen once ( ~ 15 ms czclear() )
clear both zbuffers for 2 channels.

start the drawing....

But how ?

Dietrich
