WebOpenGL provides support for the sRGB colorspace with two formats: GL_SRGB8: sRGB image with no alpha. GL_SRGB8_ALPHA8: sRGB image with a linear Alpha. These are normalized integer formats. What this means is that the values placed in images of this format are assumed to be stored in the sRGB colorspace.
