Outside the range of 0 to 1, texture coordinates return the value specified by the borderColor property.
Texture coordinates will be clamped between 0 and 1.
Between -1 and 1, the texture is mirrored across the 0 axis. The image is repeated outside of that range.
Wrap to the other side of the texture, effectively ignoring the integer part of the number to keep only the fractional part of the texture coordinate.
Options for what value is returned when a fetch falls outside the bounds of a texture.
