[Octave-bug-tracker] [bug #48195] missing getframe function

[Philip Nienhuis]

Follow-up Comment #17, bug #48195 (project octave):

@Panxto:
__osmesa_print__ probably won't save 15 sec., as it also writes to a disk file
that imread needs to read into an image "array".

IMO copying some pixel array from graphics memory into another memory piece
should always be faster. Problem of course is finding out which piece of
memory to read from. 
In the DOS era my proggies simply read graphics memory itself, i.e., various
bit planes in succession, using int10 interrupts or mem copy variants, but
those days are gone...

In spite of the side effects reported by Guillaume I'll try patch #3 anyway to
check if it works at all in Windows.
