Restored borderless window behavior where DOTA created a borderless window the size of the desktop and expected it to behave like a fullscreen desktop window.

Browse Source 
A future SDL release will change the borderless window to act more like a normal window that happens to have no chrome, to support windows that draw their own chrome. In the meantime, those applications should set the "SDL_BORDERLESS_WINDOWED_STYLE" hint.

This will also cause the task bar to overlap the window and other windowed behaviors, so only use this for windows that shouldn't appear to be fullscreen

This behavior more closely matches other platform where the window is borderless
