Upscaling is implemented in templates, so that it's compatible with multiple datatypes.
Therefore, there is no cpp file.
+
+InPlace upscaling works on a single array and assumes that the values to work on have already
+been interspersed into the array to the cell boundaries.
+Specifically, a_Array[x * a_AnchorStepX + y * a_AnchorStepY] contains the anchor value.
+
+Regular upscaling takes two arrays and "moves" the input from src to dst; src is expected packed.
