Sets a global texture property for all shaders.
Global properties are used if a shader needs them but the material does
not have them defined (for example, if the shader does not expose them
in Properties block).
Usually this is used if you have a set of custom shaders that all use
the same "global" texture (for example, custom diffuse-lighting cubemap).
Then you can set the global property from script and don't have to setup
the same texture in all materials.
By specifying a `RenderTextureSubElement`, you can indicate which type of data to set from the RenderTexture. The possible options are: RenderTextureSubElement.Color, RenderTextureSubElement.Depth, and RenderTextureSubElement.Stencil.
