if your rectangles are all horizontal then it is easy. you just use > and < on
x's and y's. if the rectangles are at randon
angles then you'll have to rotate the point in question to the coordinate system
of each of the rectangles one at a time
then use the > and < with x's and y's to see if it's inside. not difficult if
you know your trig, impossible if you don't.

Subject: sorting points or rectangles
does anybody have any idea how could i sort rectangles or points, same
problem.
i need it sorted so that when i have a lot of rectangles, i can quickly get
the ones which are inside some given big
rectangle.
