"
The FB contents doesn't get rotated, just the address space." Thanks, makes perfect sense.
Thankfully the Kindle not zeroing after a rotation allowed me to see the effect.
One could take a screenshot before a rotation, rotate the screenshot and fbink the new text over that screenshot graphics to finally be able to capture the effect. I definitely *won't be attempting this*
"
It works because each and every time, you're refreshing *just* the right region" Yeah.
"
As a quick test" Indeed.
Also of interest?? The PW3 has 3-0-1-2 top-right-bottom-left clockwise rotations and the K3 has 3-0-1-2 right-top-left-bottom counter-clockwise rotations. Go figure.
Insights much appreciated.
