Argument type mismatch between getTile[Id] and setTile/clearTile

[parasyte]

me.TiledLayer has four functions for accessing and modifying the tiles in the layer, but the x,y arguments passed to each function do not match:

• getTile and getTileId accept the coordinates in pixels
• setTile and clearTile accept the coordinates in tiles

The difference is not evident in documentation: http://www.melonjs.org/docs/symbols/me.TiledLayer.html

@parasyte based on the ticket title I just changed the documenation, but after seeing the point listed in roadmap, were you actually having in mind changing the arguments (normalize them) ?

Either one is a valid solution, I think. I figured while we were making other breaking changes, we might do this too. But I'm ok with leaving it a documentation-only change
