+### `var tex = createTexture(gl, rawObject[, format, type])`
+
+Creates a texture from the given raw element. `rawObject` is a DOM-like element that have a `raw`, `width` and `height` fields. `raw` is a value that directly get passed to `texImage2D` / `texSubImage2D`.
+
+This allows to support non-DOM implementation of WebGL like gl-headless.
