Pavel Krajcevski 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.

Pavel Krajcevski 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.

Pavel Krajcevski a80944901e Refactor CompressionJob struct. 
In order to better facilitate the change from block stream order to non-block stream order,
a lot of changes were introduced to the way that we feed texture data to the compressors. This
data is embodied in the CompressionJob struct. We have made it so that the compression job
points to both the in and out pointers for our compressed and uncompressed data. Furthermore,
we have made sure that the struct also contains the format that its compressing for, so that if
any threading programs would like to chop up a compression job into smaller chunks based on the
format, it doesn't need to know the format explicitly, it just needs to know certain properties
about the format.

Moreover, the user can now define the start and end pixels from which we would like to compress
to. We can compress subsets of data by changing the in and out pointers and the width and height
values. The compressors will read data linearly until they reach the out pixels based on the width
of the given pixel.
