Flash's drawing capabilities are slighly bugged.
At first I thought it was a JSFL problem, but the
problem can occur even while manually drawing. Execute the JSFL
below, and you'll notice I draw a gray rectangle with a black
border, then a line, then 2 touching triangles on top of the line.
Both triangles should be filled with orange, but notice only
the 2nd has any fill, and was filled oddly. If you go back one step
(Ctrl-Z), everything is fine up to that step. After the 2nd
triangle is drawn, the first loses it's fill. This only occurs in
freak coordinates about 1% of the time. If you change the order the
triangles are drawn or the coordinates slightly, it will work
If this was all manually done, I could just change it
slightly, but I'm writing code that generates JSFL, and this error
occurs too frequently to allow professional quality.
