Small game custom graphics

[TheOnyxGuy]

As you all know, R'n'D has a tiny option (no pun intended) "Small game graphics", which renders all game tiles in twice smaller size, which is neat, except the fact they appear blurry because the 32 pix tile is being downscaled to 16 pix.
So I have a little idea. What if you could do custom graphics specifically for that mode? Like, let's say, you make a custom levelset with normal 32x visuals, but for small game graphics it may even be a slightly different 16x, even more of 8-bit, style of visuals.
And one more thing: perhaps, ability to change tile size for small game as well? I mean, along with "game.tile_size: 32".
