Make a geom node from string or a node path,
put it into the 2d sg and set it up with all the indicated parameters.
The parameters are as follows:
geom: the actual geometry to display or a file name.
This may be omitted and specified later via setGeom()
if you don't have it available.
pos: the x, y, z position of the geometry on the screen.
This maybe a 3-tuple of floats or a vector.
y should be zero
hpr: the h, p, r of the geometry on the screen.
This maybe a 3-tuple of floats or a vector.
scale: the size of the geometry. This may either be a single
float, a 3-tuple of floats, or a vector, specifying a
different x, y, z scale. y should be 1
color: the (r, g, b, a) color of the geometry. This is
normally a 4-tuple of floats or ints.
parent: the NodePath to parent the geometry to initially.
