Detailed Description

The RectI class represents a 2D rectangular area using int precision.

This class is mainly used to manipulate rectangles in pixel coordinates (as opposed to real coordinates). The RectI and RectF differ in the following way:

• RectF dimensions are implemented using float precision, while RectI uses int precision.
• RectF::right() returns x()+width(), while RectI::right() returns x()+width()-1
• RectF::top() return y()+height(), while RectI::top() return y()+height()-1

• RectF
