Fix T96213: Crash when texture painting across multiple materials. 

Issue only happens in release builds on windows. That said it was an
actual error in the code. This class is compiled inline in release
builds. When updating multiple textures it would reuse the same memory
to collect the changes. When the previous loaded tilenumber was exactly the
same but from a different image the tile buffer wasn't loaded.
