I was too hasty in my reply. After some tests here are the results:

GetWindowSize returns the window client area in all platforms.

GetWindowRect here returns the full window area (decoration and borders 
included) in all the configurations tested:

Windows XP running in a VM under Linux, with Lazarus 1.2.4
Linux CentOs 6, Gtk2 and Qt, desktop KDE and XFce, Lazarus 1.2.2 and 
Lazarus 1.3 (trunk)

Apparently the documentation isn't accurate, and there's a mix-up of the 
two functions

Project planning question: when it's 90% done, are we halfway or not yet?
