//TODO:
//ABM_QUERYPOS seems to do nothing on Windows 10. It gives back the exact
//same dimensions, not adjusting for the start bar
//When the dock is docked to the left for example, it doesn't take the
//entire screen length because the start bar is there. I used ABM_QUERYPOS
//to tell me how much space Windows actually assigned to to the dock
//Since ABM_QUERYPOS doesn't work properly on Windows 10, I've decided
//to only allow the screen to be reserved when docked to top of the screen,
//with the assumption that the start bar is always on the botton of the screen
//The code is being left "as is" in case I figure out the solution to it
