Transforms X and Y coordinates with a Qt-style transformation matrix. The advantage over direct use of Qt is vectorization.

1 | ```
qvmap(m, x, y)
``` |

`m` |
A matrix encoding the transformation, or something
coercible to a matrix, like a C++ |

`x` |
X coordinates; if |

`y` |
Y coordinates, optional |

The mapped coordinates, as a two column (X, Y) matrix,
unless `y`

is missing, in which case an attempt is made to
coerce the result to the class of `x`

, if any.
