Custom Textures for 2D Filters Patch updated to current trunk - http://pasteall.org/blend/222

Blender Artists discussion thread:  http://blenderartists.org/forum/showthread.php?t=143216

Since I was here, why not ...

+ Time Node for materials
+ bgl_CameraToWorld uniform for 2D filters
+ a better 15 size big font (thanks Campbell)
+ Soft Shadows (thanks Sebastian De LA Torre (phantasmicnova))
+ a really nice splash screen (if you were at Che Blender you will recognize it :)

Everything cooked together (i.e. patch for other platforms)

Time Node test file: http://pasteall.org/blend/222

Comments and feedbacks please :)

I had some more Blender coding late night hours and I decided that the custom texture patch was stable enough for tests and feedbacks. I still have to adjust part of the code, but I don't want to spend so much time in that if this is not going to be implemented in Blender (in one way or another).

Therefore I compiled this patched "home-made" version of Blender and will need some positive return regarding how usefull this is. Can you see a good use for that? Can you produce some nice shaders with that which you couldn't do before?

If the awnser is yes, please share your artwork and opinion and we can find the better way to do this. Technical code-wise comments are very-welcome as well.

How to use it:

* Select your image using Actuator->2DFilter->Uniform Texture (temporarily the texture most be applied to any object in your scene - the object don't need to be in a visible layer though)

* Choice the name you want to use in your shader (remember: you can't use names starting with gl_)

* Enable your custom filter as usual - Actuator->2DFiter->Custom Filter

* In your shader, acess your texture using sampler2d your_texture_name;

Tip: If can use the built-in VideoTexture to change your initial texture and it will be updated in your shader as well.
