12.2 Overlapping Data Types

The Lidskjalv fragment group graphmath defines, among other things the following patterns:

• point
  which is analog to the Bifrost pattern Point
• rectangle
  which is analog to the Bifrost pattern Rectangle
• matrix, IDmatrix, moveMatrix, scaleMatrix, rotateMatrix
  which are almost identical to the correspondingly named patterns in Bifrost (they originate from Bifrost)
• ovalAngle and circleAngle
  which are identical to the EllipseAngle and CircleAngle patterns of Bifrost (also originating from Bifrost).

These overlaps in names may sometimes lead to 'Illegal Assignment' errors in compilations, and 'Qualification Error' at runtime, if you mix Lidskjalv and Bifrost code. These kind of errors may most times be solved by qualifying the references with either THIS(Guienv) or THIS(Bifrost).

In a future implementation, these attributes will have been replaced by one common set of patterns.
