* Get (and cache) positions buffer for rendering circle with various numbers of segments. * @private

* Gets (and caches) vertex shaders based on shader source code and compile time constants. * Tries to minimize the number of new vertex shaders that

* Init GLTexture/GLFramebuffer pairs for reading/writing GPULayer data. * @private

* Copy data from input to output. * This is used when rendering to part of output state (not fullscreen quad). * @private

* The base implementation of `getTag` without fallbacks for buggy environments. * * @private * @param {*} value The value to query.

* Create a string to pass compile time constants into shader. * @private

* Common code for converting vertex/fragment shader source to GLSL1. * This is called once on initialization, so doesn't need to be extremely efficie

* @param {Float16Array} float16bits * @return {number[]}

* Draw 2D mesh to screen. * @param params - Draw parameters. * @param params.layer - GPULayer containing vector data. * @param params.indices -

* Draw the contents of a GPULayer as points. This assumes the components of the GPULayer have the form [xPosition, yPosition] or [xPosition, yPositio

* Gets the native function at `key` of `object`. * * @private * @param {Object} object The object to query. * @param {string} key

* Init a simple GUI.
