Reorganized the whole pov properties, to place them in PropertyGroups, rather than cluttering the Scene/Material/etc. objects’ spaces…
Also added a new file handling the conversion from existing files using the old pov properties (call the ˘povray render: update to script v0.0.9” operator (bpy.ops.scene.pov_update_properties) in the search box of the 3d views to make the conversion).

pep8 edits for povray, also dont use string addition for textblock contents, write newlines separate.

API: 34650
fix: x-offset in one mapping of Alphamap was inverted

Some minor pep8 fixes.

Cleaned up Media and photons UI layouts

The output to Tempfiles no longer exports comments, indentations or LFs (in lists).
New option in Export settings to deactivate LF (line brakes) in lists.
Fixed a material export for normal maps. Was exported two times.
Paths to images are now realpaths, no /../ in absolut paths.

Usage: Deactivate "OS Tempfile" to see the new options.
Some UI and code cleanup. 

noticed some strange code, added XXX FIXME.

- Automatic indentation in Pov file
- Added "command line switch". (Option to set some command line parameter)

-POV file formatting improvement with UI option and function to handle all tabs/spaces indentation (big clean up)
-use of quote characters made more consistent.

Added some formatting of the pov files and some UI tweaks made by Constantin Rahn (Thanks!). Also the version number had not been updated for a while, I don't know about API number

-pov max trace level (ray depth)
-pov radiosity importance sampling
-Higher Radiosity samples count (allows Halton sampling)
-pov pretrace_start / pretrace_end
FIXED
-incomplete tooltip for pov low_error
-sky_sphere mapping options:
-world sky gradient to follow pov coordinate system
-Skysphere rotation made independant from camera
-generation of skysphere with image map and BlendSky will just consider the texture for now.

All issues reported here 
http://projects.blender.org/tracker/?func=detail&atid=469&aid=23145&group_id=153
by Constantin Rahn, except Layer selective export, adding it to maydo list

fixed two typo errors and a compatibility for gamma syntax

READ THIS TO AVOID A LOT OF WORK!

New way of linking to tracker pages: just use the parameter "aid" (artifact ID),
to avoid a lot of manual updates later in wiki and svn.

Example:
=========

OLD WAY TO LINK TO TRACKER
-----------------------------

Complete url of a script in Upload
http://projects.blender.org/tracker/index.php?func=detail&aid=25349&group_id=153&atid=467

If we move this in contrib this url will become
http://projects.blender.org/tracker/index.php?func=detail&aid=25349&group_id=153&atid=468
467 becomes 468, so we have to update this in wiki page.

Later on, when this moves into Trunk, the url will become
http://projects.blender.org/tracker/index.php?func=detail&aid=25349&group_id=153&atid=469
468 becomes 469, so we have to update the url in wiki page and svn.

Annoying!

NEW WAY TO LINK TO TRACKER
-----------------------------

Best way to link to tracker page is using:
http://projects.blender.org/tracker/index.php?func=detail&aid=25349

Use "func=detail"
Use "aid"            (which is the "artifact ID")

DON'T use "group_id" (which is the project ID, bf-extensions is project 153)
DON'T use "atid"     (which is the "artifacts tracker ID")

Like this, the url is unique, and we will avoid to update wiki pages and svn after moving pages
 


[[Split portion of a mixed commit.]]

I had forgotten to change some names I hope it does work  now; This is an adaptation of Povray exporter to render with povray 3.7 
if you want more info, there are pdfs in the zip files here on the tracker: https://projects.blender.org/tracker/index.php?func=detail&aid=22717&group_id=153&atid=468
