/**
* Refresh the texture contents from the underlying buffer storage.
*
* If the texture refers to external memory (i.e. memory owned by another
* process), the renderer may need a wlr_texture_invalidate call to make
* external changes visible to the texture.
*
* This operation must not perform any copy.
*
* If the texture cannot be invalidated, false is returned. If the texture
* doesn't need to be invalidated for external changes to be visible, true is
* immediately returned.
