1. Don't use BGRA8 unless GL_EXT_texture_storage is available …

   We recently changed to use the glTexStorage* family of functions,
   along with sized internal format types, such as BGRA8. Unfortunately,
   the GL_EXT_texture_format_BGRA8888 extension does not provide BGRA8 as
   a valid format unless the GL_EXT_texture_storage extension is also
   available, which is not usually the case on GLES3 as glTexStorage*
   are built in.
   
   Unfortunately this means we must fall back to using glTexImage* rather
   than glTexStorage* when dealing with BGRA data. Longer term it will
   make sense to ensure the provided data is in RGBA format, as the
   benifits of immutable storage are desirable.
