destroy, and false while the WebGL context is suspended

Apply a brightness adjustment.

Apply a contrast adjustment.

destroy this shader effect. Idempotent — calling destroy twice is safe. Unsubscribes from the renderer's context-lost / restored events so a destroyed effect is not auto-reactivated.
Apply a hue rotation.

Multiplies the current matrix with a transform described by individual values. Accepts either 6 values (2D affine: a, b, c, d, e, f) or 16 values (full 4x4 column-major).

A shader effect that applies a 4x4 color transformation matrix. Provides chainable color adjustment methods that automatically update the GPU uniform.
