Magnify has problems resizing

[johndrinkwater]

When reducing the size of the window, it shrinks too quickly

When enlarging the window, it often forgets the mouse move unless you move a great distance

This is probably just how Magnify behaves noramlly. Under R5 you don't notice the resize as it is set to B_OUTLINE_RESIZE that is not implemented in Haiku yet.

Magnify resized the window during user triggered window resizing - the app_server now ignores programmatic changes during that time, ie. fixed in r16743.
