The problem is that QtQuick1 uses its own pixmap cache internally, so any
change you make on QPixmapCache will have no effect. The biggest issue is
that this cache has a fixed size and it's not exposed in the public API.
So, any application that needs a bigger cache size will have to create its
own pixmap cache externally through image providers.
