In the past that worked because the `GPUMaterial` referenced the `ImageUser` from the image node. However, that design was incompatible with the recent node tree update refactor (rB7e712b2d6a0d257d272e). Also, in general it is a bad idea to have references between data that is owned by two different data blocks. This incompatibility was resolved by copying the image user from the node to the `GPUMaterial` (rB28df0107d4a8). Unfortunately, eevee depended on this reference, because the image user on the node was update when the frame changed. Because the image user was copied, the image user in the `GPUMaterial` did not receive the frame update anymore. This frame update is added back by this commit. The main change is that the image user iterator now also iterates over image users in `GPUMaterial`s on material and world data blocks. An issue is that these materials don't exist on the original data blocks and that caused the check in `build_animation_images` in the depsgraph to give the wrong answer. Therefore the check is extended. Right now the check is not optimal, because it results in more depsgraph nodes than are necessary. This can be improved when it becomes cheaper to check if a node tree contains any references to a video texture. The node tree update refactor mentioned before makes it much easier to construct this kind of run-time data from the bottom up, instead of scanning the entire node tree recursively every time some information is needed.
