chessground 3.1.0

Chess board UI developed for lichess.org. It has no chess logic inside so it can be used for chess variants.

3.1.0

• Add an optional scale parameter to arrows (default is scale: 1.0, matching the previous behavior).

3.0.0

Improve board interaction and add support for drawing shapes while playing.

Playing:

• pieces are now moved with pointer down events, instead of a tap events (pointer down followed by a pointer up event): this allows to move a piece faster
• premoves are not anymore cleared when selecting another piece: this matches lichess website behaviour and allow to prepare another move along with the premove that is currently set

Drawing shapes (experimental)

• drawing shapes is now possible while keeping the normal board play interaction (before it was either one or another mode)
• one can draw a shape by holding a finger to an empty square while using a second finger to draw a shape anywhere in the board
