d744aafb05 Added support for simulated vsync in the renderer 
This kicks in if the platform doesn't support vsync directly, or if the present fails for some reason (e.g. minimized on some platforms)

50c5d23f7d Round coordinates so very small floating point values don't turn into 0x80000000 
e.g. SDL_RenderDrawLineF(renderer, -1e20, -1e20, 10, 10);

a28f426acb render: Only update size/scale/viewport when moving to a new display, rather than all window movement. 
We really only care about DPI changes here, so this both reduces work and also avoids weird cases where viewport state can be corrupted by trivial window events. This doesn't _completely_ get rid of the issue but this is somewhat intentional, since apps will definitely want to do a full reset when changing displays anyhow (otherwise DPI/adapter changes will screw things up, and that's out of our control as long as both window size and drawable size are exposed at the same time.

Note that OpenGL still captures window events because of weird platform-specific issues like macOS and viewport stretching!

Fixes #5949
