This was not a very smart class. We replace it with a bidirectional map.

Moved ImageLoader to ResourceLoader, so that loading is extensible.
i.e. here: Zed image loader now loads up a tileset instead of being a
hacked image loader.
Goal is to support more funky stuff (wad, pak .....)

imGui docking extension tweak
tileset new getters

This is to avoid confusion with Scene::AddTile().

The old public API is maintained for now but should be considered
deprecated.

The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.

This sort of pImpl inheritance code code was weird, I got rid of it
and added a new pointer in the TileSet class instead.

- removed 18805 CR characters
 - removed 774 trailing whitespaces
 - replaced 1922 tabs with spaces
 - fixed 31 svn:eol-style properties

Added Texture (by image) update in TextureImage (and tileset)
Added lolimgui first integration pass

and 2) fuck the Visual Studio compiler that crashes when confused.

scene so that g_scene can be deprecated later.

Added palette in Scene.

Tileset : added GetTileSize().

the Scene code still breaks Direct3D rendering.

known number of tiles in a row and a column. Necessary for ticket #24.

with the Monsterz tiles.
