Offset Cylinder Generator

Generates a quarter cylinder as a .map file to be opened in GtkRadiant. This is different from the regular Cylinder Generator in that the vertices of the cylinder are rotated counter-clockwise by a half of a slice.

outerRadius:		The radius of the outside of the cylinder.
innerRadius:		The radius of the inside of the cylinder. This may be zero to generate a disk.
slices:		The number of individual brushes to be generated.
height:		How tall the cylinder is.
generateOnlySeam:		Generates only the brush at the very top of the quarter cylinder. This is the brush that extends past the plane x = 0 (the midway divider).
adjustSeamForJoining:		This affects the shape of the seam. Typically, this brush sticks out past the midline of the cylinder due to the offset. If this flag is checked, the brush is cut short by the midline (the plane x = 0), and its end vertices are moved down to lie exactly outerRadius and innerRadius units directly above the circular center of the cylinder.

	generate normal non-overlapping brushes	Generates ordinary brushes. To make a cylinder wall to fling you around at high speeds, you will have to generate overlapping brushes in order to prevent "bouncing". Another purpose for normal brushes is to define the visual component of a structure, for example by using surfaceparm nonsolid.
	generate overlapping brushes	Overlapping brushes are useful for making cylinders such that the player doesn't "bounce" off the surface when flying against the wall of the inside of the cylinder at high speeds. However, it is not advised to texture the overlapping brush faces with drawn textures. Instead, apply caulk to all of the overlapping brushes, then superimpose a set of normal non-overlapping brushes that have surfaceparm nonsolid.
