Struct FillCanvas

pub struct FillCanvas<T> { /* private fields */ }

FillCanvas is a wrapper around a matrix with special methods to fill the cells.

FillCanvas provides methods to fill individual cells with a value, or multiple cells from a row/column or just all cells within an area at once.

The filled cells have a T value != the Default::default().

PS: Initially developed to have EntityIDs (from ECS) filled into a matrix based on the space they occupy on a canvas grid.
