ns2thpoint
Draw a thick point at given position, in colour and thickness in pixels (not world coords).
Prototype
void ns2thpoint(float x, float y, float z, float red, float green, float blue, float size);
Description
Draw a thick point at the position (x,y,z) with RBG colour (red,green,blue) and thickness size pixels (not world coordinates).
