Browse source 
- When both SC_PIXEL_MODE and SC_NO_FONT_LOADING are defined,
  quietly drop SC_NO_FONT_LOADING, because the pixel(raster)
  console requires font.
- When SC_NO_FONT_LOADING is defined, force SC_ALT_MOUSE_IMAGE.
  Without font, the arrow-shaped mouse cursor cannot be drawn.
- Fiddle and simplify some internal macros.
