Represents the data source of a texture.
[page:Any data] -- The data definition of a texture. Default is `null`.
The actual data of a texture. The type of this property depends on the texture that uses this instance.
Read-only flag to check if a given object is of type [name].
When the property is set to `true`, the engine allocates the memory for the texture (if necessary) and triggers the actual texture upload to the GPU next time the source is used.
This property is only relevant when [page:.needUpdate] is set to `true` and provides more control on how texture data should be processed. When `dataReady` is set to `false`, the engine performs the memory allocation (if necessary) but does not transfer the data into the GPU memory. Default is `true`.
[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this object instance. This gets automatically assigned, so this shouldn't be edited.
This starts at `0` and counts how many times [page:Source.needsUpdate .needsUpdate] is set to `true`.
meta -- optional object containing metadata.
