I try to make one of my firsts program with Flex ...
The program is trying to display a canvas and to give the
possibility to draw a box and to resize it with the TOP_LEFT corner
(for the moment).
First pb : the box is drawing quite good until you return
slowly to the initial point, there some things like "turbulences"
Second pb : When you try to reduce the box with the TOP_LEFT
CORNER, there's a very big pb, similar than in the first pb ...
