Class description
comparison values are used in the stencil-state and depth-state and control how the fragment stencil and depth tests are performed. For the stencil test, a reference value (the value slot of the active stencil-mode ) is compared to the stencil buffer value using the comparison operator. For the depth test, the incoming fragment depth is compared to the depth buffer value.

•	cmp-always always succeeds.
•	cmp-never always fails.
•	cmp-equal succeeds if the compared values are equal.
•	cmp-not-equal succeeds if the compared values are not equal.
•	cmp-less succeeds if the incoming value is less than the buffer value.
•	cmp-less-equal succeeds if the incoming value is less than or equal to the buffer value.
•	cmp-greater succeeds if the incoming value is greater than the buffer value.
•	cmp-greater-equal succeeds if the incoming value is greater than or equal to the buffer value.
