then a call to xname returns a bitwise OR of
.S "WidthValue | HeightValue" ,
.S "XValue | YValue" ,
.S XNegative
or
.S YNegative
depending on whether the height and width are specified, whether the offsets are specified
and on the sign of the specified offsets respectively.
>>STRATEGY
For geometry strings covering each case of interest
  Parse string with xname.
  Verify that correct flags are set.
  For each value
	If corresponding flag is set
	  Verify that value is set correctly.

	  Verify that value is unchanged.
