|
|
* - loader creates two instances of collection object
|
|
* - it calls ParseDescriptor on first, then releases it
|
|
* - then it checks returned descriptor; I'm not sure, but
|
|
* it seems that DMUS_OBJ_OBJECT is not present if DLS
|
|
* collection is indeed *real* one (gm.dls)
|
|
* - if above mentioned flag is not set, it creates another
|
|
* instance and loads it; it also gets descriptor and adds
|
|
* guidObject and wszFileName (even though this one cannot be
|
|
* set on native collection, or so it seems)
|
|
* => it seems to be sort of check whether given 'default
|
|
* DLS collection' is really one shipped with DX before
|
|
* actually loading it
