Hello zou,

basically agree, but I fear these changes involve massive code

zl> getGlobalTransformationMatrix()

"global" would imply to me that this is a matrix that is globally
applied to any character (like a "master matrix") - *additionally* to
it's local matrix and of it's parents. still prefer the term "world"
in this case. Or perhaps "getFinalTransformationMatrix"()

very long name, btw..

here we come back to the original discussion, which is about "stage
matrix" being ambiguous (matrix TWIPS<->mouse or TWIPS<->renderer?)

we could also have a

  TWIPS <-> GUI <-> renderer

scenario, where "<->" is a matrix. But this would add one additional
matrix concatenation for each character during rendering.

Probably. But I would feel safe if we define "world" to describe
completely transformed coordinates in TWIPS.
