Comments

Calculates the size of the image part.

If a part can adapt to its surroundings and its maximum available space (r), it should adjust the returned size to reflect the maximum available space. For example, a string as used in the TextPartClass class can wrap around. If a part is wider than the available space, it may be clipped once it is displayed.

Calculating a part's size can be CPU intensive, in which case this routine should attempt to cache values to speed up its performance. The calc parameter can be used to distinguish the reason for the call to CalcSize, which may be helpful to cache values needed to optimize performance.
