The usual route is to use an existing text-rendering library like FreeType to rasterize your text, then upload it as a texture to the GPU and render it as a quad. If you want to do a more modern approach, you could use signed distance fields, but that requires some deep knowledge of how shaders work unless you can find an off-the-shelf library that does it for you. You may still end up needing FreeType or equivalent anyway, to get the SDFs in the first place.

Yes, it's reproducible with dmd 2.097. Trivial fix is deleting
that line `../../sdl2/gfm/sdl2/timer.d:69` then it works.
Thank, drug.
I think some like this:
env DFLAGS=-wi dub run
or like this
"buildRequirements": [ "allowWarnings" ]
without gfm/sdl2/timer.d editing.
Yes, you right. It can be removed. I will do it.
try
{
SDL2Timer timer = cast(SDL2Timer)param;
return timer.onTimer(interval);
}
catch (Throwable e)
{
// No Throwable is supposed to cross C callbacks
boundaries
// Crash immediately
exit(-1);
return 0; // <--HERE WARMING
}
It is worked! Thank!
