dzn: Only support high/normal queue priorities 

D3D uses an int which seems like it'd support value between 0 and 100,
but in reality it only accepts values of exactly 0, or 100. The space
is left in case future values were to be added, so that comparisons
would work (e.g. MEDIUM_HIGH < HIGH).

Treat higher than 0.5 to be HIGH, and anything less to be NORMAL.
