Some platform, such as Chromium, requires that the internalformat should be the same as the format in the pixel data. This limits the format should be RGBx only. If the limitation is removed in Chromium, the format could be BGRx if GL extension supports BGRx and the conversion in texImage2D could be avoided when the format in pixel data is BGRx.  
Therefore, before this patch is landed, the limitation that format and internalformat of texImage2D should be the same must be removed first.
