according to the source. The cells in the bin will receive a value that is equal
to the midpoint between the range. So a range from 0 to 10 will all have the value
of 5. Values with no data continue to be marked as NoData.

VectorToRaster uses the help of GDI+ to create a bitmap, draws the features to
the bitmap, and then converts the color coded cells to a raster format.
This is limited to bitmaps that are within the 8, 000 x 8, 0000 size limits.
Creates a new raster with the specified cell size. If the cell size
is zero, this will default to the shorter of the width or height
divided by 256. If the cell size produces a raster that is greater
than 8, 000 pixels in either dimension, it will be re-sized to
create an 8, 000 length or width raster.

Cropping will ensure that the original featureset extent plus a small extra buffer amount

The original algorithm simply allows edges that have one defined point and
another "NAN" point. Simply excluding the not a number coordinates fails
to preserve the known direction of the ray. We only need to extend this
long enough to encounter the bounding box, not infinity.
