method returns an array of strings containing the names of the ASTC profiles supported
by the implementation.
Array of string elements indicating which ASTC
profiles are supported by the implementation. Currently, this can be:
- "ldr": Low Dynamic Range.
- "hdr": High Dynamic Range.
Dynamic range refers to ratio between the brightest and darkest parts of the scene. Low dynamic ranges are for example JPEG format images which won't exceed 255:1, or CRT monitors which won't exceed 100:1. An HDR image stores pixel values that span the whole tonal range of real-world scenes (100,000:1).
const ext = gl.getExtension('WEBGL_compressed_texture_astc'); ext.getSupportedProfiles(); // ["ldr"]
