\section{Number of blits}  The number of blit operations can be expressed as:  \[T(n) = \begin{cases} 0, & n=1\\ 5 + 4 T(\frac{n}{2}), & n \neq 2 > 1  \end{cases}\] For $n = 2^x$ we try the algorithm for incremental sizes of $x$ to find a pattern for how the algorithm behaves.  \begin{subequations}
