There were a few problems with the sub texture iterating code of
sliced textures which were causing some conformance tests to fail when
NPOT textures are disabled:
• The spans are stored in un-normalized coordinates and the
coordinates passed to the foreach function are normalized. The
function was trying to un-normalize them before passing them to the
span iterator code but it was using the wrong factor which was
causing it to actually doubley normalize them.
• The shim function to renormalize the coordinates before passing them
to the callback was renormalizing the sub-texture coordinates
instead of the virtual coordinates. The sub-texture coordinates are
already in the right scale for whatever is the underlying texture so
we don't need to touch them. Instead we need to normalize the
virtual coordinates because these are coming from the un-normalized
coordinates that we passed to the span iterating code.
• The normalize factors passed to the span iterating were always 1.
The code uses this normalizing factor to round the incoming
coordinates to the nearest multiple of a full texture. It divides
the coordinates by the factor rather than multiplying so it looks
like we should be passing the virtual texture size here.

This adds a cogl_texture_set_data function that is basically just a
convenience wrapper around cogl_texture_set_region. In the common case
where you want to upload the full contents of a mipmap level though this
api takes 4 less arguments (6 in total) so it's a bit simpler.

Consistent with how we lazily allocate framebuffers this patch allows us
to instantiate textures but still specify constraints and requirements
before allocating storage so that we can be sure to allocate the most
appropriate/efficient storage.
This adds a cogl_texture_allocate() function that is analogous to
cogl_framebuffer_allocate() which can optionally be called to explicitly
allocate storage and catch any errors. If this function isn't used
explicitly then Cogl will implicitly ensure textures are allocated
before the storage is needed.
It is generally recommended to rely on lazy storage allocation or at
least perform explicit allocation as late as possible so Cogl can be
fully informed about the best way to allocate storage.

Note: This reverts the cogl_texture_rectangle_new_with_size API change
that dropped the CoglError argument and keeps the semantics of
allocating the texture immediately. This is because Mutter currently
uses this API so we will probably look at updating this later once
we have a corresponding Mutter patch prepared. The other API changes
were kept since they only affected experimental api.
There was a lot of redundancy in how we tracked the width and height of
different texture types which is greatly simplified by adding width and
height members to CoglTexture directly and removing the get_width and
get_height vfuncs from CoglTextureVtable
