Fluid 0.7.3 — a user interface library, now with a reworked I/O system

[Artha]

I would also like to address, following discussion in the last 
topic, that improvements to Fluid's text layout engine will be 
added in Fluid 0.8.0. Once I do that, I plan to create a generic 
interface for text rendering (as an I/O system) before I make 
further adjustments. This way, it would be possible to experiment 
with external systems (such as Pango) before committing to 
another large-scale project.
