Viewport: Labels for measure are hard to read

[softyoda]

The text of edge lenght isn’t readable when used with default blender background. It’s only visible when there is a object behind (cf screenshoots)

I don’t use measure tool as i don’t found it convenient, so i always add a plane, merge all its point to center and enable edge lenght.

I think it need white contour or at least add options to set color for the text.
This applies for all kind of measure, Ruler Tool also.
