Summary 0001915: Effect of matrix bottom row in Transforms module
Description In the Transforms module, a value larger than 1.0 in the bottom row of a transform matrix (perspective projection part of the matrix) does not always make its effect in the other coordinates when an additional translation is applied. All values in the result matrix are capped by the Min Max values of the translation sliders when the sliders are changed.
This function worked correctly in Slicer 3.

Several places in Slicer core and extensions the bottom row of the matrix is ignored (assumed to be [0 0 0 1]). Therefore, the cleanest solution would be to make the bottom row read-only in the GUI.
