Plugin works fine here on macOS 10.11.6 with QGS 2.14. Thanks for putting
it together. Glad to see it works cross-platform without quirks!

Here on macOS, the clipboard contents are recognized as a TIFF-formatted
image (of course, not GeoTIFF, that would be too cool - though I don't know
where one could *paste* a GeoTIFF). Guessing that the clipboard format
might be platform-specific and managed by Qt.

Also here on macOS, there is a thin gray border, which I think is always
part of the widget's scene. IMO actually makes the capture better, if there
is a partial or wrapped white background shown in the canvas and the user
is pasting into a white-background document (common scenario).

Richard, if you are looking to add this to master, maybe it should go under
the View menu, e.g. View -> Copy to Clipboard (maybe right under 'Zoom
Out'?), since Edit menu seems to be just for editing features and is fully
greyed-out if only working with rasters. Another appropriate menu might be
Project -> Copy to Clipboard, under 'Save as Image...', though I think
under View is maybe better.

Be good to have a default key binding, though I can't think of a decent
cross-platform keystroke right now.
