### prda_ComputeTextTransformMatrix

Computes a new text transform matrix from the character attribute bundle stored in the display context instance, and puts the new transform in the instance as well. This function recalculates the transform from scratch. This is necessary when any of the cell size, angle, or shear entries in the character attribute bundle change.

Warnings:

The transform matrix that is created will be suitable for converting points from Adobe style (1000x1000) units to world coordinate space. Because often the values already in world coordinate space need only to be rotated, the cosine and sine values that are calculated are also saved.
