virtual bool Update(const UpdateDesc* updates, unsigned count = 1, unsigned mipLevel = 0);
Update updates a texture region based on the specified image data. The first method updates texture by copying the provided data into it, only one mip-level can be updated at a time. The second method performs a full image update by calling the associated Image::Decode.
Texture update proceeds in four (optional) steps:
1. Image::Decode - Done unless rescaling directly from RawImage.
2. Rescale - Done if non-power of two textures are not supported as necessary.
3. Convert - Needed if conversion wasn't applied in Decode.
4. SWF Mipmap generation - Loop to generate SWF mipmaps, may also have a convert step.
