Bugfix: The "Convert to Premul"-Button was drawn twice for Images...

Step one in bringing back Yafray Render in Blender. Need someone else
to take over now, but I'm available for help. Main notes for completing:

- Yafray module uses old global R all over... is now a pointer handle.
It can be temporally bypassed by straight copying, which I do now.

- I am not sure in what pixel format Yafray renders... Blender now only
uses float buffers. In the code, marked with XXX I've added the
rudimentary code for retrieving buffers.

- This integration will skip compositing when Yafray render is used.

More render pipeline finishing up;

- Shaded drawmode is back (shift+z).
Note it still only uses orco texture; but lighting/shading is using
the internal render module entirely.

- "Make Sticky" option back.
(Also fix in sticky texture render, was wrong scaled)

saveRenderedImage is broken? - isnt working anymore for some resion. switched back to renderAnim.
More efficient texture usage, packer now rotates the convex hull of the UV's for each image to fit the most image into the smallest rectangle.

Added a 2d convex hull function to BPyMathutils
Added a 2D Line intersection function
Added a function to BPyMesh that gets the mesh space vertex location of a Faces UV Pixel.

comments on how edge weighting for collapsing works.
uv_auto_layout_tex now uses the recently fixed saveRenderedImage - I needed to make clean and make to get it working.

Use Kens hide/sel mesh props to save some python looping.

===Python API===
Added to Mesh API me.sel and me.hide, which set/clear the selection and
hidden values for all verts/edges/faces in a mesh.

===Python API===
Fixed epydoc summaries for mesh.vert.index and mesh.vert.uvco so they say
something useful other than "(MVert Only)".

Bugfix in last commit; preview renders didn't work render properly, parts
of tiles were black sometimes.

===Python API===
Bugfix: epydocs for World API incorrectly described settings for getMode(),
setMode() methods.

Fix spelling error in tooltop.

Poly reduction fixes
Added remove doubles as a keyword option,
Fixed Triangulate (need to select the faces first)
Fixed boundry weighting (defaults reduced boundries first more then
non boundry verts!)
Made face area weighting give better results.

So! Finally time to work on finishing render pipeline project.
This commit brings back:

- Field Render
- MBlur Render (old style)
- Border render with or without cropping

Note: Field Render is not supported in Compositor yet. Blurring or filter
will destroy field information.
Both MotionBlur as Field render are done before Compositing happens.

Fixes:

- The "Save Buffers" option only worked on single frame renders, not for
Anim render.
- Found an un-initalized variable in Render initialize... this might have
caused the unknown random crashes with render.

Code restructure:

Cleaned up names and calls throughout the pipeline, more clearly telling
what goes on in functions.
This is visible in the updated first image of the Wiki doc:

* bug fix
[ #4228 ] Blender.Image.Load(filename) loads only on the first loading
- Image.Load() will now reload the image buffer when a image of the same name is loaded again
- small textual change in render code

==md2 export update==

[ #4237 ] MD2 export Light Normal is rotated incorrectly fixed by Bob Holcomb

Slight simplification of windowtype_pup()...

*python fix
- save_rendered_image_cb_real has a popup window embedded in it that prevents automation through python as a result python scripts would get a popup which is ignorned by the script
- modified so python scripts overwrite the image by default

- bug fix
* C uses braces unlike python :/
