|Summary||0001256: Order of operations for Matrix is nonintuitive, needs documentation|
|Description||The intuitive effect of|
m = Base.Matrix ()
shape = shape.transformGeometry (m)
would be a move followed by a rotate. In other words, the same as if those two transformations had been built in two separate matrix objects and applied by transformGeometry in that order.
In fact, the result of this code is a rotate followed by a move -- as if the operations had been reversed when the combined transformation matrix was constructed.
Is this intentional? If yes, it needs to be documented because it is surprising (at least to me -- allow for the fact that I'm not experienced with CSG).
If not, it would be nice to fix this (with a release note, since it affects scripts written around the existing behavior).
