Text doesn't always fit into the canvas

[MichaCo]

Hi guys,
First of all thanks for implementing this almost the moment where I actually needed it ;)

Unfortunately the canvas seems to be fixed size with a width of 300px. This means, that bigger labels might not fit into the canvas and simply get cut off (no wrapping -.-)

Could we at least have an option to control the width?

Or, as I fixed it for now, set the canvas.width to 1000px. For labels which are centered, the works just fine.

Thanks
M
