Bug 683514 - Add support for the GL_EXT_unpack_subimage extension. r=joe A GLES 2.0 extension exists that allows us to use GL_UNPACK_ROW_LENGTH, amongst other variables. This really helps us when uploading sub-regions of a buffer that don't span the entire width of that buffer (for example, when scrolling horizontally). This extension is available on Android tablets, and possibly other Tegra 2 devices, so is very much worth taking advantage of.
