1d7bf727ff Fix #32695: Can't disable color management for 3D view
Made it so viewport will disable color management if display device set to None.

This solves couple of regressions, mainly related on old BGE files and made
None display behave exactly as old color management disabled.

a73dd3476e Color Management, Stage 2: Switch color pipeline to use OpenColorIO
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.

This introduces two configurable color spaces:

- Input color space for images and movie clips. This space is used to convert
  images/movies from color space in which file is saved to Blender's linear
  space (for float images, byte images are not internally converted, only input
  space is stored for such images and used later).

  This setting could be found in image/clip data block settings.

- Display color space which defines space in which particular display is working.

  This settings could be found in scene's Color Management panel.

When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.

This conversions are:

- View, which defines tone curve applying before display transformation.
  These are different ways to view the image on the same display device.
  For example it could be used to emulate film view on sRGB display.

- Exposure affects on image exposure before tone map is applied.

- Gamma is post-display gamma correction, could be used to match particular
  display gamma.

- RGB curves are user-defined curves which are applying before display
  transformation, could be used for different purposes.

All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.

This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).

Some technical notes:

- Image buffer's float buffer is now always in linear space, even if it was
  created from 16bit byte images.

- Space of byte buffer is stored in image buffer's rect_colorspace property.

- Profile of image buffer was removed since it's not longer meaningful.

- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
  to support other spaces, but it's quite large project which isn't so
  much important.

- Legacy Color Management option disabled is emulated by using None display.
  It could have some regressions, but there's no clear way to avoid them.

- If OpenColorIO is disabled on build time, it should make blender behaving
  in the same way as previous release with color management enabled.

More details could be found at this page (more details would be added soon):

6ccc605660 Bicubic bump map filtering.
This commit introduces bicubic bump map capabilities for the viewport for OpenGL 3.0+ capable GPUs. 

To use the functionality change the bump mapping method to "best quality"
Previous "best quality" setting becomes "medium quality" now.
For non OpenGL 3.0 GPUs this becomes the same as "medium quality"

Also:
* added tooltip descriptions to the bump method settings.
* modified the shader to ommit extraneous matrix multiplications for matrices already provided by OpenGL.

28ee0f9218 Texturing: texture and 3d view draw type changes, these should only have any
effect for a render engine using new shading nodes. In short:

* No longer uses images assigned to faces in the uv layer, rather the active
  image texture node is what is edited/painted/drawn.
* Textured draw type now shows the active image texture node, with solid
  lighting.
* Material draw mode shows GLSL shader of a simplified material node tree,
  using solid lighting.
* Textures for modifiers, brushes, etc, are now available from a dropdown in
  the texture tab in the properties editor. These do not use new shading nodes
  yet.

b263aefb0e TexFace to Material Settings big patch
Summary:
========
The idea here is to move the texface options into the material panel.
For images with the change please visit:
http://code.blender.org/index.php/2011/09/bge-material-texface-changes

1 - Some of the legacy problems 2.49 and 2.5x has with the texface system:
==========================================================================
1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can
select a face to be more than one mode.
1.2) Sort only works for blend Alpha yet it's an option regardless of the
Transparency Blend you pick.
1.3) Shared doesn't affect anything in BGE.
1.4) ObColor only works for Text objects (old bitmap texts) when using Texture
Face Materials. (not address yet, I so far ignored obcolor)

2 - Notes:
============
2.1) Now "Use Face Textures" in material Option panel will work in Multitexture
even if there is no texture channel.

2.2) In FaceTexture mode it will use TexFace all the time, even if you don't
check the "Use Texture Face" option in the UI. It's a matter of decision, since
the code for either way is there. I decided by the solution that makes the
creation of a material fast - in this mode the user doesn't need to mess with
textures or this "Use Texture Face" option at all. I'm not strong in my opinion
here. But I think if we don't have this then what is the point of the Texture
Face mode?

2.3) I kept references for tface only when we need the image, UV or the tiling
setting. It should help later when/if we split the Image and UV layers from the
tface struct  (Campbell and Brecht proposal).

3 - Changes in a Nutshell:
==========================
3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set.

3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …).

3.3) New options in the Material Panel
* Shadeless option in the Material panel is now supported for all three Shading modes.
* Physics is now toggleable, this is the old Collision option.
* Two Side (on) is now called Back Culling (off).
* Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid).
* Shadow, Billboard and Halo are grouped in the “Face Orientation” property.
* "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually).
* The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties.

4 - Acknowledgment:
==================
Mike Pan for the design discussions, and testing along the whole development process.
Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that.
Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).
Blender artists that gave feedback and helped testing the patch.

01744abd81 GPU: add gpu python module with export_shader() function to export GLSL shader.
shader = gpu.export_shader(scene,material) 

Returns the GLSL shader that blender generates to produce the visual effect
of material in scene for the purpose of reusing the shader in an external engine.
This function is meant to be used in a material exporter so that the GLSL
shader can be exported entirely. The return value is a dictionary containing the
shader source code and all associated data. 

The full documentation is under sphinx.

Warning: there has been an API between the patch and this commit:
uniform['lamp'] and uniform['image'] now return python reference to 
ID block instead of ID name as before. The X3D exporter that uses this
function must be adapted.

6926060185 - fix for BL_Shader::SetUniform() missing out the last part of the matrix.
- particle.c wasn't setting all components of the vector when reading cache and setting dummy velocity values.
- some functions incorrectly took a float[3] argument when the 4th value was set.
- remove a few redundant lines of code.
