Disable SourceValidate in rotation to capture cursor.

Browse Source 
SourceValidate is used exclusively by the software cursor code to pull the
cursor off of the screen before using the screen as a source operand. This
eliminates the software cursor from the frame buffer while painting the
rotated image though. Disabling this function by temporarily setting the
screen function pointer to NULL causes the cursor image to be captured.
