Most users of morphic are not aware that
MatrixTransform2x3 does trmendously aggressive
rounding and truncation when transforming points in
the normally accepted manner.

This seems strange and I suspect there are several
bugs and screen gribbles connected to the unaware use
of this behavior.

evaluate in a workspace:

results := 
{ IdentityTransform identity 
. MatrixTransform2x3 identity
 . MorphicTransform identity } collect: [ :each |
    ( -2.0 to: 2.0 by: 0.25 ) collect: [ :eachOne | 
          (each globalPointToLocal: (each
localPointToGlobal: eachOne asPoint )) ]] .


Yours in service, --Jerome Peace
