As Cam said, we discussed this on IRC.  My position is that
the polygon fill routine does not belong in Mathutils.

Strictly speaking, Draw is the bpy interface to OpenGL.  If we are not
going to create a new module, Draw is probably a better place than
Mathutils.

Scan conversion is a necessary step before rendering a polygon.  I
would argue that a routine to scan-convert a polygon more properly
belongs in a rendering or geometry utility module than Mathutils since
it is not strictly a mathematical operation like matrix inversion, for
example.

I am less concerned about initially creating a new module with only a
single member than I am with getting the module structure correct and
sensible.  Other things that could end up in a Geometry module are
analytic geometry utilites like intersection tests and conveniece
routings for creating geometric objects.

Ken has a valid point about adding new functionality during
a CVS freeze without any preceding discussion.
