specific size increments... on_configure

[rob <rob robstoddard com>]

I would like to have my little video-showing widget to size in specific 
increments because of interlaced video.  The problem is, if the widget 
is free to be any size, what will happen is that the widget will hit a 
harmonic of any deinterlacing artifacts in the case that interlaced 
video is being delivered to the widget.  This causes a very obvious and 
annoying wave effect to appear on any object that's moving horizontally 
in the image.

I would like to constrain the widget's size to specific increments and 
aspect ratio, but would like it to resize according to the suggestion of 
its parent.  Is there a way to do this gracefully?


Thank you for your support,
