Geometry types and algorithms.

Special thanks to:

Tomasz Stachowiak (h3r3tic): allowed me to use parts of omg.
Jakob Øvrum (jA_cOp): improved the code a lot!
Florian Boesch (___doc__): helps me to understand opengl/complex maths better, see: http://codeflow.org/.
#D on freenode: answered general questions about D.

Note: All methods marked with pure are weakly pure since, they all access an instance member. All static methods are strongly pure.

TODO: Support radian and degree types (from units-d package)

TODO: Use sink as param in toMathML and toLaTeX

TODO: Replace toMathML() with fmt argument %M to toString functions TODO: Replace toLaTeX() with fmt argument %L to toString functions

TODO: Optimize using core.simd or std.simd TODO: Merge with analyticgeometry TODO: Merge with https://github.com/CyberShadow/ae/blob/master/utils/geometry.d TODO: Integrate with http://code.dlang.org/packages/blazed2 TODO: logln, log.warn, log.error, log.info, log.debug TODO: Make use of staticReduce etc when they become available in Phobos. TODO: Go through all usages of real and use CommonType!(real, E) to make it work when E is a bignum. TODO: ead and perhaps make use of http://stackoverflow.com/questions/3098242/fast-vector-struct-that-allows-i-and-xyz-operations-in-d?rq=1 TODO: Tag member functions in t_geom.d as pure as is done https://github.com/D-Programming-Language/phobos/blob/master/std/bigint.d TODO: Remove need to use [] in x[] == y[]
