SetTransform: PROC [context: Context, transformSpace: ImagingSpace,

transform: TransformRecord];

fast for setting common types of flips and rotates

GetTransform: PROC [context: Context, transformSpace: ImagingSpace]

RETURNS [TransformRecord];

ConcatToContext: PROC [context: Context, transformSpace: ImagingSpace, transform: Transformation];

for rolling your own transforms

Transform: PROC [transform: TransformRecord, p: Vec] RETURNS [Vec];

InverseTransform: PROC [transform: TransformRecord, p: Vec] RETURNS [Vec];

TransformVec: PROC [transform: TransformRecord, p: Vec] RETURNS [Vec];

InverseTransformVec: PROC [transform: TransformRecord, p: Vec] RETURNS [Vec];

IntTransform: PROC [transform: TransformRecord, p: IntVec] RETURNS [IntVec];

InverseIntTransform: PROC [transform: TransformRecord, p: IntVec] RETURNS [IntVec];

TransformIntVec: PROC [transform: TransformRecord, p: IntVec] RETURNS [IntVec];

InverseTransformIntVec: PROC [transform: TransformRecord, p: IntVec] RETURNS [IntVec];
