[HTML5] Fix broken layout on load in HiDPI screens

Browse source 
This was caused by the devicePixelRatio being applied twice, once by the
HTML code, once by the OS code.
More specifically, OS.get_window_size() would return the canvas element
size, while OS.set_window_size() would set the element size to the
specified value times the devicePixelRatio.
Calling OS.set_window_size(OS.get_window_size()) would reapply the
devicePixelRatio every time.
This commit changes the behaviour so that OS.set_window_size() do not
apply the devicePixelRatio to the canvas element size, by it divides the
CSS size instead.
