Fix blur scaling

Commit 0e1702ad7a6a827d "Add ass_set_storage_size and fix related scaling issues"
attempted to fix blur scaling. This breaks blur scaling for players
which don't call ass_set_storage_size().

This commit reverts the default behavior to the old behavior. The
behavior when ass_set_storage_size() is called should be unchanged.
