Detailed Description

DepthSortCallback sorts the primitives of the Geometry bound to the Actor in which the callback is installed.

In order to work properly DepthSortCallback requires the following:

Despite the fact that the condition list seems to be quite limiting it actually covers the most common usage cases. Furthermore the use of DrawElements* and the primitive types PT_POINTS, PT_LINES, PT_TRIANGLES, PT_QUADS grants the maximum flexibility.
