System Information
Windows 7
Geforce GTS 250

Blender Version
Broken: 9337574, 60d2492, f2a7c2f and others

Short description of error
When making a vertex paint brush stroke, the further away the view is from the object, a strange effect is produced when the view is then moved. The image shows the result after painting the whole visible part of the object black, then zooming in.

(also the edge of the viewport acts like a mask for vertex painting, I don't know if that's intended behavior though)

Exact steps for others to reproduce the error
Paint on the object (the view should already be far) then move the view.

@Psy-Fi, @ideasman42, is it something known to you guys? Looks like it's kinda precision issue of raycasting from the brush, which only pics single pixel of the texture instead of doing upscaling?

It looks like the good-ole-OpenGL based selection for faces that we paint on. But I would consider this more TODO because we'd need to almost rewrite vertex paint to fix this.

Archiving since it's a TODO. Note, I'm now working on PBVH based vertex painting which should solve this.
