Improved hitboxes and terrain

Improved hitbox and terrain solidity display.

Lua HUD for TASing Monster World IV v0.10.001

This is the first version of a HUD for TASing Monster World IV, a game that (until recently) was only released in Japan. This version supports:

• basic information display: position (down to subpixels) and speed (for both
  Asha and Pepe), hearts (including blue), life drops, gold, post-hit
  invulnerability counter and Pepe's level.
• infinite jump automation: with Pepe one frame away from being grabbed,
  leave A in auto-hold and hold down left mouse button on double arrow button as
  you frame advance; Pepe will be once again one frame away from being grabbed,
  and you can chain this. The sequence was chosen that maximizes average speed.
• hitbox display: shows collision box (in white), interaction box (in
  various colors, generally smaller), Asha's sword hurtbox, the base offset of the
  object (top two digits), hit counter and invulnerability timer (for enemies),
  gold range (for gold) and collection delay (for general treasure, including gold).
• jump prediction: what Asha's speed will be like after pressing C for
  the next two frames.
• terrain solidity: a colored overlay over the different solidity types.
  Top solid = green, right solid = maroon, top and right solid = olive,
  left solid = blue, top and left solid = teal, right and left solid = purple,
  all but bottom solid = gray, all solid = white.
