-   * TODO(dave): un-private this when there is a way to actually override the
-   * shader used for points
-   *
-   * Get the shader used when drawing points with <a href="#/p5/point">`point()`</a>.
-   *
-   * You can call <a href="#/p5.Shader/modify">`pointShader().modify()`</a>
-   * and change any of the following hooks:
-   * - `void beforeVertex`: Called at the start of the vertex shader.
-   * - `vec3 getLocalPosition`: Update the position of vertices before transforms are applied. It takes in `vec3 position` and must return a modified version.
-   * - `vec3 getWorldPosition`: Update the position of vertices after transforms are applied. It takes in `vec3 position` and pust return a modified version.
-   * - `float getPointSize`: Update the size of the point. It takes in `float size` and must return a modified version.
-   * - `void afterVertex`: Called at the end of the vertex shader.
-   * - `void beforeFragment`: Called at the start of the fragment shader.
-   * - `bool shouldDiscard`: Points are drawn inside a square, with the corners discarded in the fragment shader to create a circle. Use this to change this logic. It takes in a `bool willDiscard` and must return a modified version.
-   * - `vec4 getFinalColor`: Update the final color after mixing. It takes in a `vec4 color` and must return a modified version.
-   * - `void afterFragment`: Called at the end of the fragment shader.
-   *
-   * Call `pointShader().inspectHooks()` to see all the possible hooks and
-   * their default implementations.
