- Don't set InitParams::TRANSLUCENT_WINDOW. Setting this resulted in
  the WS_EX_COMPOSITED style being added and the WS_THICKFRAME style
  being removed, which disabled Aero Snap.
- Remove the non-client border to get a completely frameless window.
  Having a border is problematic because the top is drawn by Windows
  while the rest is drawn black. Having Windows draw part of the
  border is required to enable the window drop shadow (see
  HWNDMessageHandler::SetDwmFrameExtension).
- Delete the remove_caption patches which are no longer required.
