+Shape is 32-bits. When SHAPE is set entirely to zeros, remapping is
disabled: the register's elements are a linear (1D) vector.

-applydim will set to zero the dimensions less than this. applydim=0 applies all three. applydim=1 applies y and z. applydim=2 applys only z. applydim=3 is reserved.

+z. applydim=3 is reserved.
-invxyz will invert the start index of each of x, y or z. If invxyz[0] is zero then x-dimensional counting begins from 0 and increments, otherwise it begins from xdimsz-1 and iterates down to zero. Likewise for y and z.
+invxyz will invert the start index of each of x, y or z. If invxyz[0] is
+zero then x-dimensional counting begins from 0 and increments, otherwise
+it begins from xdimsz-1 and iterates down to zero. Likewise for y and z.
-modulo will cause the output to wrap and remain within the range 0 to modulo. The value zero disables modulus application. Note that modulo arithmetic is applied after all other remapping calculations.
+offset will have the effect equivalent to the sequential element loop
+to appear to run for offset (additional) iterations prior to actually
+generating output.
xdimsz, ydimsz and zdimsz are offset by 1, such that a value of 0 indicates
that the array dimensionality for that dimension is 1. A value of xdimsz=2
