Detailed Description

Geometric class.

Library: xviews or winviews or mviews (mutually exclusive)

IlvRoundRect is a rectangle IlvRect with rounded corners. Each corner is a IlvRoundRectCorner. Corner radiuses can't be greater than rectangle's dimension. For instance the addition (top left corner width + top right corner width) can't be greater than rectangle width. Therefore:

When rectangle's dimensions are modified, corner radiuses are reduced if needed.
Set or modified corner dimensions are controlled and reduced if necessary. Corner dimensions are reduced proportionally in each edge, and the maximum radius attainable is set. For instance if the addition (top left corner width + top right corner width) is greater than rectangle width, both top left corner width and top right corner width are going to be reduced proportionally.
