Display scaled sprites of static objects

[facundoolano]

• load a list of static objects from the map into the game (this is necessary because it can change: items dropped or picked up) (spotvis in wolf4sdl)
• object should have both view xy and tile xy
• update raycaster to mark all visible tiles in a boolean matrix
• for each static object:
  • check if is visible from raycaster output matrix
  • if it is, calculate height based on distance to player (TransformTile in wolf4sdl)
• port ScaleShape (similar to already ported simple_scale_shape)
  • pass ray hits to get wall heights (aka occlusion array)
  • only draw a given pixel column when sprite height > wall height at that x coordinate
