Clarify that a window being 'hidden' means that it is unmapped/ordered out

Browse Source 
SDL considers a hidden window to be unmapped and blocks or defers certain operations until the window is shown again, however, the X11 and Cocoa backends would set the hidden flag when the window was minimized, which blocked the functionality of SDL_RestoreWindow().

Specify that a window with the hidden flag set is unmapped and not visible on the desktop or in the dock/taskbar without a call to SDL_ShowWindow(), and don't set the hidden flag in the X11 and Cocoa backends when the window is in the minimized state, but still mapped to the desktop.
