WindowServer: In HighDPI mode, load high-res window buttons and high-res cursors
Bitmap::load_from_file("foo.png", 2) will now look for "foo-2x.png" and try load that as a bitmap with scale factor 2 if it exists. If it doesn't, it falls back to the 1x bitmap as normal. Only places that know that they'll draw the bitmap to a 2x painter should pass "2" for the second argument. Use this new API in WindowServer for loading window buttons and cursors. As a testing aid, ctrl-shift-super-i can force HighDPI icons off in HighDPI mode. Toggling between low-res and high-res icons makes it easy to see if the high-res version of an icon looks right: It should look like the low-res version, just less jaggy. We'll likely have to grow a better API for loading scaled resources, but for now this suffices. Things to check: - `chres 640 480` followed by `chres 640 480 2` followed by `chres 640 480` - window buttons in window context menu (in task bar and on title bar) still have low-res icons - ctrl-shift-super-i in high-res mode toggles sharpness of window buttons and of arrow cursorf - arrow cursor hotspot is still where you'd expect
