Re: [ngl-devel] Very nice but very slow

Hi Vince ;)

nuiEditText doesn't use the nglFontLayout directly and we found that 
constructing a nglFontLayout object is painfully slow as hell.
Even with that we currently draw the glyphs one by one which is far from 
efficient for the video card.
Going from nglFont1 to nglFont have been quite a perf hit for nui. Maybe 
we are not using it correctly and you could advise us after a quick look 
at the code?
