Description:
Moves the pointer to a given offset from the end of the layer. The first parameter is the number of units to move and the second is the unit (see the Fixed Size Method). Thus (FromEnd 4 Bits) would move the pointer 4 bits prior to the end of the layer while (FromEnd 4 Bytes) would move the pointer 32 bits from the end of the layer. Both parameters are optional and, if omitted, will default to zero and Bytes.
