/*
* This alternative dumpframe was created to:
* 1) allow coloring by all particle properties
* 2) change brightness scaling to be be a number that
* a| increases with brightness
* b| is in the range 0-1
*
* To allow access to more properties, I removed a lot of the
* portability features, so that now I pass PKDs and PARTICLEs
* into the dfRender_____ functions.
*
* The brightness scaling now relies on the dMinGasMass.
