Rotating Polygons

[MisterX]

Nice Alex,

I didn't know that rev handler existed! ;)

To avoid the precision problem, just keep the original coordinates
unrotated.

It's ok for scale or translations but not for rotations. Do the rotation on
a copy of the original object and not the last rotated set. So you only get
just one precision approximation. 

Im too am working on a vector graphic library! ;)

get the short id of graph x
get polyPointArray[polyid] -- x,y[,z,...] table, ndim array

-- get move deltas and offsets from original, not last position...

get MovePoly([moveOffsetXYZ] [,pointsArrayXYZ]
get ScalePoly([ScaleXYZ] [,pointsArrayXYZ][,centerXYZ,]
get SlantPoly([rotationXYZ] [,pointsArrayXYZ][,centerXYZ]
get RotatePoly([rotationXYZ] [,pointsArrayXYZ][,centerXYZ]
put it into graph x

Precomputing helps for speed issues too...

Hope that helps ;)

Cheers
Xavier
