{This unit provides some common matrix and vector operations on vectors and
 matrixes with dimensions of 2, 3 and 4 which are the most common ones in
 computer graphics, and all routines provided in variations with single,
 double and extended precision.

 The goal of this unit is also to invite some standardisation
 between libraries, i.e. a vector from library x can be passed to library y
 without conversion routines in between.

 It would be nice to have some diehard assembler optimized versions of
 these routines, however the Free Pascal team wishes to concentrate on the
 compiler. Contributions from the community are very welcome.}
