Re: is there a way to reassign a SDL2 source value in a program?

iOS also provides a UITouch.tapCount property (“the number of times the user tapped their fingers on a certain point within a predefined period”), which is not used by SDL at all but would be exactly what I expect to be exposed by the SDL mouse event clicks field.

Double-click speed on desktops is typically a user-exposed system wide setting, so I feel like SDL’s APIs should expose that information rather than doing something that a developer using SDL can do on their own.

I'm not sure of the current status of SDL_GetDisplayDPI (It doesn't seem to work in Android) so if that's not available I can see there might be a problem.
