Gamma correction
Should the font image values be gamma-corrected for standard displays (i.e. sRGB) instead of being linear intensities? In other words, should the values be linear_to_srgb(intensity)?
It isn't very hard to filter the values when creating the font images – this can be done with a 256-byte lookup table – and would be a lot faster than doing so when using the values to create the fonts.
The characters look better and less blurry after gamma correction for sRGB displays.
Yeah, I messed around with gamma encoding a bit when I was writing a physically-based renderer a few months ago, and gamma correction is absolutely vital for any kind of realistic render.
Gamma correction is not such a huge deal for standard GUIs, but I noticed that the font on low-PPI displays looks a lot better with gamma correction.
Shall I create a pull request for that?

Yes, I will appreciate that very much!
