Raise the term number cap in the Matrix tool

I know I asked this before, but is it possible to increase the number of terms we can add to the matrix tool?
@pgaudet @RLovering and I are trying to improve the generic GO slim. Putting the terms into the matrix tool is a great way to assess the modularity (reduced overlap between slim terms).
At present we have too many terms:

@ValWood Honestly, I'm not sure if I remember this specifically from before; poking around a little isn't turning up much.

About how many would you need? Unfortunately, without rewriting a whole bunch of the core here, there is not a lot of flexibility--the code is unfortunately tweaked with a lot of hard-coded values in a library I'm not particularly familiar with anymore. That said, I may be able to do something like increase the base canvas size or double the density without much additional work, depending on what your expected needs are.

We can let you know the final number once we have the slim set It is likely to be around 70-75 ball-park for process.
cheers,

I went hunting for the old ticket but I couldn't find it anywhere...
