A customer of mine had the strange problem, that SDL_SetRelativeMouseMode() was failing for him on Windows 7. Luckily he was willing to provide some debug informations. We could track this problem down to RegisterRawInputDevices() failing due to security software running on his system (Norton Internet Security to be precise, but there are reports of similar problems with other products. For example [1]). Working around this issue with SDL_WarpMouseInWindow() is easy, and while I don't think that SDL2 can provide an internal workaround it would be really nice and helpfull if this could be documentated somewhere.

I think SDL could (and should!) do the warping itself automatically as a fallback if RegisterRawInputDevices() fails.
It's shouldn't be up to the SDL user to add platform-specific hacks.

Hey Ryan, I recently added the mouse warping mode to SDL. Should we fall back to that, do you think?

Ugh, yeah, let's do that. Should we get this into 2.0.2?

Yes, this is a good fix to get in.

Okay, if RegisterRawInputDevices() fails, we'll transparently fall back to mouse warping.
