1. Changes :

• Added opacity settings of sprites previews into plugin parameters.
• Added a new plugin command parameter "Complex Shape". This is for users who want to place complete custom shaped group of tiles. While the "Shape" parameter was basically drawing a rectangle of the inputted size of what is in your tileset, this "Complex Shape" parameter let you define what tile at which position in the group you want to build. 

     2. Bug fixes :

• Fixed a bug where you couldn't switch tiles if several placeable tiles was set on the same spot on restricted mode.
• Fixed a bug where you couldn't place tiles if sprite preview was disabled on free and restricted mode.
• Fixed a bug where you couldn't place tile on free mode if you put regions ids on restricted mode parameters.
• Fixed a bug where you could only place a shaped tile on restricted mode on the spot that has the corresponding region id.
• Fixed a bug where shaped tiles would not be placed at the good position on free mode if the player was facing the left direction.

     3. Optimization : 

• Optimized verification of region ids while placing a tile on free and restricted mode.
• Optimized bitmap sprite preview refresh only when needed.
• Optimized calculation of shaped sprite preview autotiling.
