Nicer matrix rendering

* fix float type bug in transform routine (Single=float32<>float)
* Increase matrix and vector columns from 7-2 to 9-2
* Render infinity and negative infinity with proper symbols, NaN/missing values with a cross (can be changed to something else of course if you have a better idea).
