Description

The GR32_Transforms unit uses $3\times 3$ matrices to represent 2D homogeneous coordinate transformations (translation, rotation, scaling, skewing, and projective mapping).

• TFloatMatrix: $3\times 3$ matrix using 32-bit floating-point precision (TFloat).
• TFixedMatrix: $3\times 3$ matrix using 16.16 fixed-point precision (TFixed).
• IdentityMatrix: $3\times 3$ constant identity matrix ($M_{i,i}=1$, $M_{i,j}=0$).
