Clip children/siblings patch.

[Rein Klazes]

Hi,

Another fix for Agent 2.0 beta.

Some buttons on Agent's preference dialogs did not display. Found that
it is caused by the buttons having a WS_CLIPSIBLINGS style and therefore
were clipped by a group with a WS_EX_TRANSPARENT ex-style. Testing shows
that windows excludes child windows with this ex-style from the
CLIPSIBLINGS clipping and also if their parents have WS_CLIPCHILDREN
style.

Changelog:
	dlls/x11drv	: winpos.c
	In clip_children() don't clip the visible region by children
	that have a WS_EX_TRANSPARENT style.

Rein.
