*******************
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.

* Lamp duplication is not supported: if you have duplicated lamps in your scene
(i.e. lamp that are instantiated by dupligroup, etc), this element will only
give you a reference to the orignal lamp and you will not know which instance
of the lamp it is refering too. You can still handle that case in the exporter
by distributing the uniforms amongst the duplicated lamps.
* ["image"] : :class:`bpy.types.Image`
Reference to the image databloc. Set for uniform type :data:`gpu.GPU_DYNAMIC_SAMPLER_2DIMAGE`. You can get the image data from:
.. code-block:: python
# full path to image file
uniform["image"].filepath
# image size as a 2-dimensional array of int
uniform["image"].size
* ["texnumber"] : integer
Channel number to which the texture is bound when drawing the object.
Set for uniform types :data:`gpu.GPU_DYNAMIC_SAMPLER_2DBUFFER`, :data:`gpu.GPU_DYNAMIC_SAMPLER_2DIMAGE` and :data:`gpu.GPU_DYNAMIC_SAMPLER_2DSHADOW`.
This is provided for information only: when reusing the shader outside blencer,
you are free to assign the textures to the channel of your choice and to pass
that number channel to the GPU in the uniform.
* ["texpixels"] : byte array
texture data for uniform type :data:`gpu.GPU_DYNAMIC_SAMPLER_2DBUFFER`. Although
the corresponding uniform is a 2D sampler, the texture is always a 1D texture
of n x 1 pixel. The texture size n is provided in ["texsize"] element.
These texture are only used for computer generated texture (colorband, etc).
The texture data is provided so that you can make a real image out of it in the
exporter.
* ["texsize"] : integer
horizontal size of texture for uniform type :data:`gpu.GPU_DYNAMIC_SAMPLER_2DBUFFER`.
The texture data is in ["texpixels"].
* ["attributes"] : sequence
list of attributes used in vertex shader, can be empty. Blender doesn't use
standard attributes except for vertex position and normal. All other vertex
attributes must be passed using the generic glVertexAttrib functions.
The attribute data can be found in the derived mesh custom data using RNA.
Each element of the sequence is a dictionary containing the following elements:
* ["varname"] : string
name of the uniform in the vertex shader. Always of the form 'att<number>'.
* ["datatype"] : integer
data type of vertex attribute, can be one of the following:
* :data:`gpu.GPU_DATA_2F` : use glVertexAttrib2fv
* :data:`gpu.GPU_DATA_3F` : use glVertexAttrib3fv
* :data:`gpu.GPU_DATA_4F` : use glVertexAttrib4fv
* :data:`gpu.GPU_DATA_4UB` : use glVertexAttrib4ubv
* ["number"] : integer
generic attribute number. This is provided for information only. Blender
doesn't use glBindAttribLocation to place generic attributes at specific location,
it lets the shader compiler place the attributes automatically and query the
placement with glGetAttribLocation. The result of this placement is returned in
this element.
When using this shader in a render engine, you should either use
glBindAttribLocation to force the attribute at this location or use
glGetAttribLocation to get the placement chosen by the compiler of your GPU.
* ["type"] : integer
type of the mesh custom data from which the vertex attribute is loaded.
See attribute-type_.
* ["name"] : string or integer
custom data layer name, used for attribute type :data:`gpu.CD_MTFACE` and :data:`gpu.CD_MCOL`.
Example:
.. code-block:: python
import gpu
# get GLSL shader of material Mat.001 in scene Scene.001
scene = bpy.data.scenes["Scene.001"]
material = bpy.data.materials["Mat.001"]

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.
