[Extendflash] Matrix Rotation and Custom Tool problems.

[Chris Fourney]

It looks like its shrinking at about .1% every degree I rotate it. I guess I need to take this into account and have every rotation also check its height and width and keep these constant? What exactly does this age old flash bug do? Just shrink the object per rotation?
   
  Any help on my rotation matrix function will also be greatly appreciated. It works as a command, but not as a function within a tool. Did I acidentally leave a counting variable that doesnt clear each time? I didnt see any. Is there an easier way to rotate a matrix around an arbitrary x,y point? without the const method? I need it to rotate in reference to its current position and not in reference to its original matrix identity position. But it also has to rotate while keeping its current scale and skew -- if you use the normal rotation matrix (cos, sin, -sin, cos), it sets the symbol back to its original scale -- it needs to maintain the scale and skew. And more than anything else, it needs to rotate at a certain point. Im using x1 = cosd*x - sind*x; y1 = sind*x + cosd *y (d is delta, the angle), but since Im using the contat method on the matrix to apply the transformation, I define this a little backwards. It seems this contat doesnt want to work within the tool.
   
  Sadly, Im using MX 2004 -- and this tool needs to work for MX 2004, so I dont have the flash.geom.matrix or the flash.geom.transform class and I cant use them to rotate or transform the matrix (matrix.transform, matrix.rotate, ect).

How much are they shrinking? There's an ages old Flash bug that symbols 
will shrink a tiny bit after each rotation, I'm guessing that is 
probably what's happening with your tool.
