Occlusion queries are usually used in a depth only pass so the attachments changing is a better indication of the query block ending.
Write mask changes are also considered since some games do depth only pass by setting 0 write mask on all the colour targets.
Tries to reset returned queries in background when possible, rather than ending the render pass.
Still ends render pass when resetting a counter after draws, but maybe that can be solved too. (by just pulling an empty object off the pool?)
May avoid issues with drivers with NVIDIA on linux/older gpus on windows when using large buffers (?)
Also some performance things and fixes issues with opengl games loading textures weird.
