Title: grabcut.py sample: Allow drawing rect from bottom/right

The grabcut sample script isn't able to create rectangles correctly that are
drawn from e.g. bottom-right to top-left.
This small commit uses four min() calls to determine the correct
top-left point of the rectangle.
It also removes some unnecessary white spaces before colons.
