I suggest using the FP emulation library for starters. Changing Mesa to
only use fixed point would be a very big job, and probably messy.

There isn't an up to date document describing the Mesa source
organization. In fact, since Keith's T&L overhaul I don't
think there's any one person who completely understands all the
code anymore (including me!).
When you have a (detailed) question ask here.
