[hatari-devel] Mouse scaling fix + ST_LOW_RES video boost

[David Savinkoff <dsavnkff@xxxxxxxxx>]

Hi,

This patch contains the Hextracker Mouse fix
AND
A selectable ST Low Res performance enhancement.

De-Selecting "Keep Desktop Resolution" enables the enhancement
(the Atari or SDL must also be reset OR toggled Fullscreen/Desktop).

Note that "Keep Destop Resolution" says Falcon/TT only,
this enhancement is for ST_LOW_RES only.

This enhancement makes ST Low Resolution look better in
TV quality and gives better perfomance in VGA and RGB quality.
Low speed computers really benefit from this. Please consider.

Thank You,
David Savinkoff
