1.	I created a ppm file in PovRay to use as a heightfield. When I used it
in a test scene I got this error.

 File: C:\Graphics\Moray For Windows Beta\PovScn\type02.pov  Line: 86
  height_field {

    ppm  "C:\data\images\type010.ppm" <----ERROR

Parse Error: Unsupported number of colors (0) in PPM image.

Returned from renderer with error status

It seems strange that there is a problem reading from a file that PovRay
generated itself. 

2.	Another problem is with the pgm format. If the file (in ASCII) has a
comment character "#" I get this error.

Parse Error: Invalid width or height read from PPM image.

If I use ASCII format I can edit out the comment lines so it's no bid deal but
it would be nice not to.
