WebStencil formats can only be used for Textures if OpenGL 4.4 or ARB_texture_stencil8 is available. Reading from a stencil-only texture is treated as reading from a one-component unsigned integer texture. So you must use usampler* types when accessing them, just as for accessing the stencil component of depth/stencil textures. Required formats WebOpenGL requires that textures all have a 4-byte alignment e.g. their size is always a multiple of 4 bytes. Normally this won't be a problem since most textures have a width …
