=> R0 = pointer to path block
R1 = pointer to output path block, or 0 to overwrite the input
R2 = pointer to transformation matrix, or 0 for default
R3 = 0
<= R0 = R1 = 0 R0 corrupted
else pointer to end of path marker in output path
This SWI is a subset of Draw_StrokePath, in that it only transforms a path. This can save the time taken to repeatedly transform the same path, or reduce errors by transforming before dashing and thickening.
