Parameters:- tex:
A runtime texture handle.
- fileName:
The file name of an image to load, or a base64 "data:" URL. This should preferably be a PNG, and has to be specified as a file
in the resource manifest.
Returns: TRUE for success, FALSE for failure.
Replaces the pixel data in a runtime texture with the image data from a file in the current resource, or a data URL.
If the bitmap is a different size compared to the existing texture, it will be resampled.
This command may end up executed asynchronously, and only update the texture data at a later time.
