rectangle sizes are broken, probably for compatibility with BeOS:
they do not round up in a reasonable fashion, and they return the
numerical difference between the end and start sides in both
directions, instead of the actual size.
For example:
BRect (1, 1, 5, 5).IntegerWidth ()
Will return 4, when in reality the rectangle is 5 pixels wide,
since the left corner is also a pixel!
All code in Emacs should use the macros below to calculate the
dimensions of a BRect, instead of relying on the broken Width and
Height functions. */
