[Bf-python] Patch: Draw.Image() -- new method.

[Jonathan Merritt]

Hi Everyone,

Attached is a patch to implement a Draw.Image() method to draw 
Blender.Image objects using OpenGL raster operations.  A brief 
description of the Python API (it's documented properly in Draw.py) is 
as follows:


Blender.Draw.Image(image, x, y, zoomx=1.0, zoomy=1.0, clipx=0, clipy=0, 
clipw=-1, cliph=-1):

   Draws a Blender.Image on the screen using raster operations.

   (image) - Blender.Image to draw.
   (x, y) - Raster coordinates of the lower-left corner of the image 
(can be negative).
   (zoomx, zoomy) - Horizontal and vertical zoom factors.
   (clipx, clipy, clipw, cliph) - Image space clipping rectangle.


Please let me know what you think.  I know we're in CVS freeze at the 
moment, so I can re-submit after the release if necessary.  I would 
really like a method with this functionality to use in my camera 
calibration script.

Thanks,

Jonathan Merritt.

PS - I submitted this to the bf-blender mailing list, but I think that's 
the wrong place. :-]
