The OES_texture_half_float_linear extension for WebGL 1.0 contexts adds linear filtering with half floating-point pixel types for textures.

The OES_texture_half_float extension for WebGL 1.0 contexts adds texture formats with 16-bit (also known as half float) and 32-bit floating-point components.

The EXT_texture_filter_anisotropic extension for WebGL 1.0 and 2.0 contexts adds anisotropic filtering (AF). AF improves the quality of mipmapped texture access when viewing a textured primitive at an oblique angle.

The ANGLE_instanced_arrays extension for WebGL 1.0 contexts draws the same object multiple times or groups of similar objects multiple times, if the group shares the same vertex data, primitive count and type.
