The primitive manager contains spatial data structures used to efficiently render primitives. Once a primitive is constructed, it must be added to the primitive manager before it will be rendered.

Add	Adds a primitive to the manager. Primitives must be added to the manager to be rendered.
Clear	Removes all primitives from the manager.
Contains	Determines whether the manager contains a primitive.
Remove	Removes a primitive from the manager. The primitive is no longer rendered unless it is added back into the manager.

Count	Gets the number of primitives in the manager.
PrecisionExponent	Gets or sets the exponent used to compute the maximum precision for primitive rendering. For example, a value of -3 indicates the maximum precision of 2^-3, 0.125 m along the x, y, or z axis. The worst case precision, taking into account all axes, is sqrt(3 * (2^-3)^2), 0.2165 m. The default is -2.
TranslucentPrimitivesSortOrder	Gets or sets the sort order for translucent primitives in the primitive manager. This determines a trade-off between rendering speed and quality. It is only recommended to use PrimitivesSortOrderBackToFront when translucent primitives along the same line of sight cause blending artifacts.
