Lagrange is nice but why does it use so much memory?

There is certainly room for improvement in the memory use department.

Possible reasons:


	Bugs. I wouldn't rule out a memory leak or too lazily freed buffers somewhere.
	Aggressive buffering of visible content. Copies of the visible regions 

of the page and sidebars (with 50% extra) are kept in memory for quick redrawing.

	Custom text rendering. All the fonts are loaded to memory (19 MB of TTF 

data), and furthermore there is quite a large cache of used glyphs for 
quickly drawing them.

	The navigation cache is kept in memory, including full contents of gemtext pages.
	Something I've overlooked? I'll investigate...

Honestly why sending this on the much broader gemini mailing list and
not on Lagrange's proper support channels (mailing list/issues/irc
channel etc)?
