Feature request for DSP (PPI settings under 50)

[yaddatrance]

In the older versions of lasercad I was able to specify PPI under 50 (e.g. 32 PPI)

The new versions cap it at a minimum of 50, I use low PPI to mark areas of interest or make tear-off sheets on paper (Can't use the dash option instead cause it jerks terribly causing oscillation)
