Maybe I’ve forgotten how computer graphics work, or I am not being clear
enough. In MXML, if you specify:
<Rect left=“0” right=“0” top=“0” bottom=“0”>
<stroke>
<SolidColorLine thickness=“2” />
<stroke>
</Rect>
then regardless of the size it is drawn, there will be a two-pixel line
around the rectangle, which is what I think you want (assuming you size it
and don’t scale it). A scroll thumb would have other logic to center any
“grip” graphics.
That’s because under the covers, the code will call drawRect(0, 0, width,
height), which I think is what you want.
I would expect SVG to be able to do something similar.
