getExtension of WebGL shouldn't return any

[kyasbal]

TypeScript Version: 2.4.0

Code

This is part of lib.d.ts.

    getExtension(name: string): any;

But, there are also several type definitions of extension returning value.

interface WEBGL_compressed_texture_s3tc {
    readonly COMPRESSED_RGB_S3TC_DXT1_EXT: number;
    readonly COMPRESSED_RGBA_S3TC_DXT1_EXT: number;
    readonly COMPRESSED_RGBA_S3TC_DXT3_EXT: number;
    readonly COMPRESSED_RGBA_S3TC_DXT5_EXT: number;
}

declare var WEBGL_compressed_texture_s3tc: {
    prototype: WEBGL_compressed_texture_s3tc;
    new(): WEBGL_compressed_texture_s3tc;
    readonly COMPRESSED_RGB_S3TC_DXT1_EXT: number;
    readonly COMPRESSED_RGBA_S3TC_DXT1_EXT: number;
    readonly COMPRESSED_RGBA_S3TC_DXT3_EXT: number;
    readonly COMPRESSED_RGBA_S3TC_DXT5_EXT: number;
};

interface WEBGL_debug_renderer_info {
    readonly UNMASKED_RENDERER_WEBGL: number;
    readonly UNMASKED_VENDOR_WEBGL: number;
}

declare var WEBGL_debug_renderer_info: {
    prototype: WEBGL_debug_renderer_info;
    new(): WEBGL_debug_renderer_info;
    readonly UNMASKED_RENDERER_WEBGL: number;
    readonly UNMASKED_VENDOR_WEBGL: number;
};

interface WEBGL_depth_texture {
    readonly UNSIGNED_INT_24_8_WEBGL: number;
}

declare var WEBGL_depth_texture: {
    prototype: WEBGL_depth_texture;
    new(): WEBGL_depth_texture;
    readonly UNSIGNED_INT_24_8_WEBGL: number;
};

These objects are not used.

    getExtension(name:"WEBGL_depth_texture"): WEBGL_depth_texture;
    getExtension(name:"WEBGL_debug_renderer_info"): WEBGL_debug_renderer_info;
    getExtension(name:"WEBGL_compressed_texture_s3tc"): WEBGL_compressed_texture_s3tc;
    getExtension(name:string):any;

This must be fixed with like the code above. There are more extensions also, these also should be defined in lib.d.ts.

looks like there are more extensions available: https://www.khronos.org/registry/webgl/extensions/

I still need to merge the change into the main TS repo
