* Headers/Additions/GNUstepGUI/GSTheme.h: New GSThemeMargins struct.

Browse source 
Rename buttonBorderForCell:style:state: to buttonMarginsForCell:style:state:
and return the top/bottom/left/right margins instead of just two values.
(This is a theme API break.)
* Source/GSThemeDrawing.m: Implement buttonMarginsForCell:style:state:.
Also reduce the top and left margin of the default button by 1 pt, to
better reflect the button's appearance.
* Source/GSGuiPrivate.h: Add a GSRoundTowardsNegativeInfinity function
* Source/NSButtonCell.m (-drawImage:withFrame:inView:): Round the image
position down and to the right, as this seems to look the best.
* Source/NSButtonCell.m (-cellSize): Call new buttonMarginsForCell: method
* Source/NSButtonCell.m (-drawingRectForBounds:): Call new
buttonMarginsForCell: method
