WebGL extension #NN
Written against the WebGL API 2.0 specification.
Implementations must also support the EXT_texture_norm16 extension.
When this extension is enabled:
texSubImage2Dentry points taking
HTMLImageElementare extended to accept the pixel type
UNSIGNED_SHORT, with associated internal format being one of
HTMLImageElementto pixel type
UNSIGNED_SHORTwith associated internal format being one of
RGBA16_EXTthrow a DOMException.
HTMLImageElementwith fewer channels than that indicated by the internal format result in channel expansion where red, green, and blue channels are populated with 0 and alpha channel is populated with 0xffff. Uploading image sources with more channels that that indicated by the internal format would result in channel clamping.
HTMLImageElementfile format is PNG only at present.
