Summary:  Anchoring values is miscalculated

Original Submission:  After some diggin' into the issues with the anchoring in 
winforms, reported by Simon Guindon and described in 
http://dotgnu.org/pipermail/developers/2004-November/012576.html
I was able to narrow it down being caused by the 
prevParentWidth/prevParentHeight values in a child control is updated with new 
values without the actual bounds of the control is updated, resulting in the 
distance between the child bounds and it's parent increases.

I was able to *fix* this with not allowing not more than one call to 
InitLayout() (see attached patch), as it was called multiple times and this 
updating the fields as described above.

However, I'm not so familiar with the layout engine and uncertain how this 
could affect real-world applications and thus I'm asking for some comments and 
testing results on this patch so we, hopefully, can elimating creating more 
bugs :)
