Re: [Tuxpaint-devel] [Tuxpaint-maintainers] Moving from SDL 1.2 to SDL 2.0

[TOYAMA Shin-i. <sh...@wm...>]

Hi!

As I wrote in https://sourceforge.net/p/tuxpaint/bugs/200/, 
using SDL2 surely solve overscaling problem on High resolution
windows pc.

Recently I have read an article by those who are using TuxPaint
using eye tracking device for kids with disabillities, explaining 
that this problem forces them to set screen scale 100%.

This strongly motivated me to switch to SDL2 ;-)

Thanks!
