There are several problems.
Some window managers define the width and height including the border, some
without, and there is no easy way to find out. It seems getting better, so
at least it works under the most common wm.
Then come the hen and the egg problem: To determine the needed ClientHeight,
you need the theme and the font size, which needs the Handle, which needs
the ClientHeight.
And some window managers do not allow free resizing of windows, only in non
'ugly' steps.
And last but not least: Calculating the correct ClientHeight can depend on a
lot of data, which a LCL interface may not have implemented yet for all
cases. The gtk and win32 interfaces are getting stable and complete, but we
already get three new interfaces: qt, wince and carbon.
Of course programmers don't want to wait years, until these interfaces get
the state of the gtk/win32 interfaces. Programmers want to use the IDE and
the LCL with their favorite interfaces, even if there are some ugly todos.
