dd41fc6ba1 Finish first pass of ASTC decompressor 
Added color unquantization, the partition selection function, and the
actual lerping of colors once the texels have been decoded.

1f5cb9294c Add ASTCEncoder tests 
Start with small tests to make sure that integer sequence encoding is working the way
that it needs to. Ideally there will be many more tests here, but for now we are trying
to get ASTC decompression working and testing is not a priority.

5a68febdda More work on ASTC decode. 
Fixed the notion that the CEM data was right after the first six bits
after the partition mode. It's actually right before the texel weight
data. Still not sure whether or not the texel weights are read in
the opposite order from the color data...

Also, added some preliminary integer sequence decoding. This will need
to be tested before we actually figure out if we did it correctly or not...

7ed5c13405 Allow additional indexable types 
Instead of using operator() to index into the second operand of the
VectorAddition function, use operator[]. This way we can add to pointers
and std::vector types as well.

62cce58c2f Fix some of the vector multiplication and divide routines. 
In general, we want the scalar division of vectors and matrices to
have the matrix come first and the scalar come second. It doesn't make
sense to divide a scalar by a vector or to divide a matrix by a vector,
so these should now produce errors at compile time.

Also, make sure to add additional types that can be multiplied together
using the * operator. If we multiply two vectors together, that's a dot
product. The size restrictions should be enforced at compile time by the
template parameters for VectorBase<T, N>::Dot

In this way, we can support vector/matrix multiplication by retaining the
* operator as well.
