GPv3: Draw Tool: Replace "Input Samples" with "Spacing"

Browse Source 
The GPv2 draw tool used a setting called "Input Samples" to
generate points (subdivisions) when two samples are far apart
from one another.

In GPv3 we have the same feature, but with a bit more control.
Users can now specifiy the maximum distance between two
points based on a percentage of the brush size (in pixels).
