Assigning the value of a float to an unsigned int is undefined
behavior unless the value is guaranteed to fit. We run afoul of this
in compute_grad_points(), where the number of steps is computed using

steps = the maximum value of an unsigned int, when really this should
be an error case resulting in steps = 1. The test suite catches this.

The svg was causing more path elements to be generated in the internal
representation than space was allocated for and overrunning heap
blocks.

The path element parsing was using a fixed size allocation for the
path elements and never bounds checked. Further it did not cope with
zero length paths (which the spec says are permitted). It was also
grossly overallocating for the common case.

This changes the path element array to be bounds checked and then
extended if required, the initial allocation is generally sufficient
and in testing very few resizes occurred.

The reallocation strategy grows the element storage by 2.5 each time
this means even in the degenerate case very few reallocations are
required. In testing no more than a single reallocation has been
observed.

The final path element array will always be reallocted to the minimum
required size. This reduces overall memory usage which is useful with
