[PATCH 0/6] Misc display/sm501 clean ups and fixes

[BALATON Zoltan <balaton@eik.bme.hu>]

Hello,

These are some small clean ups and changes to hopefully improve 2D
engine performance and fix a security bug in it. I've only tested it
lightly, haven't verified if breaking it is still possible. It's also
known to change handling of right to left blits which may not be able
to handle overlaping regions but the only guest known to use it
(AmigaOS on sam460ex) seems to be OK with this so unless this is
proven to be needed I won't try to fix that now, this could be
addressed in later patches.

Regards,
BALATON Zoltan
