Fixed bug in getclientdimensions:
In conformance with conventions for the RECT structure, the bottom-right coordinates of the returned rectangle are exclusive. In other words, the pixel at (right, bottom) lies immediately outside the rectangle. git-svn-id: http://www.villavu.com/repositories/merlijn/mufasa@23 3f818213-9676-44b0-a9b4-5e4c4e03d09d
