Short-cuts for corner movement send wrong coordinates

[bullar]

In my case the travel limits are set to x=0...295, y=0..175
If in GUI I click on FRONT LEFT CORNER button for instance the expected position is sent [G53 G21 G0 X5 Y5] but in case of short-cut ‘Go to Front Left corner’ negative coordinates are sent [G53 G21 G0 X-290 Y-170] which causes alarm.

Here data for all 4 corners:

FRONT LEFT
G53 G21 G0 Z-1
G53 G21 G0 X5 Y5           GUI
 G53 G21 G0 X-290 Y-170     Short-cut

FRONT RIGHT
G53 G21 G0 Z-1
G53 G21 G0 X290 Y5         GUI

BACK RIGHT

This should be fixed in the next release.
