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 that is a multiple of 4 and/or use 4 bytes per pixel, but since we now only use a single byte per pixel, the texture can have any possible width. WebOpenGL is a low-level API which requires the programmer to tell it the exact steps needed to render a scene. You cannot just describe a scene and have it displayed on your monitor. It …
