As seen in the attached picture (mesh.jpg), mesh layer rendering of vector arrows will sometimes miss arrows along the edge. I assume this is because those fall just, just outside the canvas extent.

IMHO, the requested extent from which arrows are drawn need to be a buffered canvas extent value, possibly canvas extent + maximum lenght of a vector arrow, to insure the rendering is accurate.

(As per discussed on hangout, assigning this to mesh-master Peter)
