@ -15,13 +15,19 @@ However, upscaling usually requires generating the "1 +" in each direction.
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.
