Tab as Space as a User Preference option. to affect new and loaded text files.
* I put it under General->System. Not sure is the better place for it though (space_userpref.py)
** also: creator.c fix to avoid autoplay of games when scripts are disabled.

BGE 2D Filters: slightly change dfelinto patch to use SCA_IScene instead of KX_Scene. It is rather anecdotic since KX_Scene is the only implementation of SCA_IScene but it's better to keep GameLogic and Ketsji separated.

re-project: operators for projecting from a view screenshot rather then a camera.
- new mode for projecting an image with the view matrix saved in the image id-properties rather then using the camera matrix.
- operator to screenshot the view and create a new image with the view matrix stored in the image.

these will be used for better re-project integration and are not immediately very useful.

disallow naming ID datablocks an empty string, this wont work, you cant select them in the ID user input and it can mess up writing files based on names.
also fixed some warnings.

Full Path for GL include, fixing compile for scons.

Note: /include doesnt have a scons script yet, so fixing it this way.

python api function for rna objects: object.as_pointer()

This means we can write low level apis in pyton or C where blender data is passed to external C modules without having to have blender support this directly.

Example use case is to get an image pointer then use ctypes to get the image buffer and pass it to a C image processing function.

RNA/Py API from 2.4x
Image functions: reload(), update(), gl_load(), gl_free()

Fixed memory leak caused by incorrect adding data to mesh's layer in nurbs_to_mesh().

pep8 cleanup

Fix for #21420, Minor bug with editing keymaps

Disable add item button for non-editable keymaps

Bugfix for #21466, paste and copy ramps doesnt work

Fixed typo

reproject
- use render mesh settings rather then view settings.
- fixed bug with brush size being overwritten and allowing non mesh objects to be projected onto.
- made the paint loop less messy & minor cleanup

reprojection
- blend in the projected image by its alpha rather then copy its alpha. this way you can easily mask out areas not to touch.
- undo was crashing.

bug from own commit 27277, ortho wasnt being disabled in render data once set.

Bugfix for #21452, Crashdown in Video Sequence Editor

Added some NULL checks

reproject operator, use to reproject edited renders back into textures.
- uses project paint options (UV bleed, normals, culling)
- bicubic interolation from the image
- multithraded

TODO.
project into multiple objects at once.

Constructive modifiers for curves and surfaces

Used approach with creating DerivedMesh for curves whet they've got such modifiers.

Available modifiers are: array, edge split, mirror, solidify, subsurf.

Fix #21458: tangent space normal maps didn't work correct in some
cases due to recent fix to avoid division by zero.

Fix #21442: RNA mesh texture face layer was giving corrupt data while
in edit mode. Accessing this data would require editmesh wrapping, so
for now just don't allowed this to be accessed in edit mode.

Fix #21374: OS X Makefiles missed optimization flags in 2.5 since at least
two years, got (presumably) commented out for some test and never added back.
