Parsing
The parsing functionality is for saving and loading from a custom file format.
The BNF for the custom file format is below.
Terminals are surrounded by ** to the left and right. (rule)+ means "1 or more".
int ::= (0-9)+
item ::= **{** int int int int int int int int **}**
layer ::= **[** item **]**
layer_tree ::= int int **{** (layer)* **}**
The first two ints in the grid int int **{** (item)+ **}** always follow the order: canvasWidth canvasHeight.
The large number of ints in the item always follows the order: x y ex ey r g b a.
