* Removed display::screen_area(), display::w(), and display::h(). * Moved the global screen_area() function into the CVideo class. * Renamed CVideo::getx() and gety() to get_width() and get_height() * Made those two functions return the result of screen_area() instead of the other way around. * Added preliminary support for high-DPI rendering to screen_area() Note on the last point: When I fixed bug #1772 (aa8f6c7e7 right now but will probably change with rebasing) I noted that SDL_GetWindowSize and SDL_GetRendererOutputSize returned the same results for me (even with Window's automatic scaling for non-high-DPI-enabled apps disabled) but that the SDL documentation stated the former returned screen coordinates and the latter pixels. In that same commit I changed the dimension functions to use SDL_GetWindowSize. I've now reversed that decision and gone back to using SDL_GetRendererOutputSize so I can guarantee output in pixels. If use_pixels is false, the code will return coordinates in 96 DPI, so I need to have pixel measurements for the calculations. Again, though, I do not know if SDL_GetWindowSize returns a different value that pixel size (which it's said to do) on macOS or iOS. I'll need to do some testing. It's possible on those platforms I won't need the 96 DPI measurements, but it's also possible it will be needed on on platforms, since all of our code relies on pixel measurements.
