The following tables will use abbreviated type descriptions, such as:
- vec2 - an array of two numbers.
- ivec2 - an array of two integers.
- rgba - an array of four integers in the range *\[0..255\]* denoting RGBA constituent colors.
- rgba - an array of four integers in the range `[0..255]` denoting RGBA constituent colors.
