Checks if a Triangle and a Line intersect.

The Line intersects the Triangle if it starts inside of it, ends inside of it, or crosses any of the Triangle's sides. Thus, the Triangle is considered "solid".

@function Phaser.Geom.Intersects.TriangleToLine
@since 3.0.0

@param {Phaser.Geom.Triangle} triangle - The Triangle to check with.
@param {Phaser.Geom.Line} line - The Line to check with.

@return {boolean} `true` if the Triangle and the Line intersect, otherwise `false`.
