Detailed Description

The D_Geo_Line_2D class represents a 2D line and offers usefulls methods for standard tasks for 2D points and lines.

Supports homogenious coodinates. Calculation is done homogenious/inhomogenious, whichever is easier. From user perspektive, this is irelevant and handled internally.
