Reduce the minimum width from 10 to 1

I like having a simple cpu usage monitor on my panel. This plugin works well for that use case, but the one problem I have with it is that to get the graph to be 5 px wide instead of 10, I had to get the source of the plugin, edit cpu.h in panel-plugin, and change the MIN_SIZE from 10 to 1 which would let me set the width to whatever I wanted. I don't know why this isn't in the plugin, everything seems to work perfectly except for maybe the margins, which I can fix in part with some text wizardry like hair spaces.

I attached pictures of 1px, 5px and 10px widths. You can see the 5px widths work great with the overall size of the panel as well as with the gpu graph next to it. 10px looks disproportionately large.
