Adding more sand borders in floortiles

[Seyjin]

Tiles were missing for several sandborders in floortiles. I have added.
I did not see any problem in game due to the change in image size.

this needs to be implemented in the code, so the tiles are used by the game :)

I would have thought that this should actually be implemented in the same way as shadows... the sand being a transparent overlay that can be put on top of neighbouring tiles.

This would allow transitions between sand and any other floor type that is introduced in the future, and requires fewer component edges and corners as the various combinations can be constructed on the fly.

agree to @Ampa

or by using rotations

+1 @Ampa
on an expansion to this idea could we separate each floor tile to its own texture file which would include generic transitions.
so at a later date we could add QuickSand, CutStone, Dirt, Grass or RoughStone etc and have them transition from one to another without having an exponential increase in required textures.
all we would need to do is give each Tile a priority value so we always know which way to do the transition.
