FlagBits is just the name of the enum. The actual data type representing a combination of these flags follows the *Flags convention. (The relevant difference is that the latter is defined to be uint32_t instead of left implicit) For consistency, use *Flags everywhere instead of randomly switching between *Flags and *FlagBits. Also fix a wrong type name on `stageFlags`, pointed out by @atomnuker
