De'Casteljau and Splines

De'Casteljau and Splines

Should have committed ages ago, but got distracted by other things happening.

Performance test shows Goldman's algorithm is really slow.
Because he is making a bigger matrix and then inverting it multiple times.
Other than that it is the same as De'Casteljau anyway.

Splines are a thing. Tried to work them out myself, ended up just copying the algorithm from wikipedia.

Quad trees are a thing that I have seen before (Barnes Hut; efficient N-body simulations).
In a graphics context they are a way to work out what parts of a scene to render? Maybe look at them more.

TODO: Decide exactly on scope for project.

All I can think of is implementing the "document viewer" on a mobile device. Not sure I want to do that...
Design of document format / viewer should come before putting it on a mobile device anyway.

Will waste some time by looking at PostScript some more for now.
