Ensure that the cached GPU texture inside the image matches the pass, layer, and view of the given image user, if not, invalidate the cache such that the next call to the GPU texture retrieval functions such as BKE_image_get_gpu_texture updates the cache with an image that matches the give image user.
This is provided as a separate function and not implemented as part of the GPU texture retrieval functions because the current cache system only allows a single pass, layer, and stereo view to be cached, so possible frequent cache invalidation can have performance implications, and making invalidation explicit by calling this function will help make that clear and pave the way for a more complete cache system in the future.

Get the #GPUTexture for a given Image.
The requested GPU texture will be cached for subsequent calls, but only a single layer, pass, and view can be cached at a time, so the cache should be invalidated in operators and RNA callbacks that change the layer, pass, or view of the image to maintain a correct cache state. However, in some cases, multiple layers, passes, or views might be needed at the same time, like is the case for the realtime compositor. This is currently not supported, so the caller should ensure that the requested layer is indeed the cached one and invalidated the cached otherwise by calling BKE_image_ensure_gpu_texture. This is a workaround until image can support a more complete caching system.
