Add Position Setting within WDialog
I used WDialog in my project to popup a form or a table.
I noticed WDialog is parentless, and in style sheet, its "position: fixed".
But if the content is beyond the scale of screen, part of the dialog would be overrided.
I tried add a overflow to .Wt-dialog, but in polished theme horizontal scroll bar will always appear, due to the drop_shadow outset.
Now I change its "postion" to "absolute". Still need some job to adjust its "top" not to be negative.
Can we make a initial position setting for WDialog, and set if it's fixed or attached to parent Container?
P.S. WScrollArea not working in a WDialog yet.
