Render mask does not work when render area set to blow up or crop

Basically as the title says, the render mask only works when the area to render is set to view.
The same is true for the region render tool in the VFB, it has no effect in a crop or blow up render.

Thanks for the feedback, I'll make sure we have that into our bug tracking system.
I would like to clarify that V-Ray Render Region doesn't work hand in hand with Area to Render set to something different than region.
Render Mask however does work with it, all modes except Texture should operate in the familiar way. Texture render mask will also work but the texture placement will use the output parameters instead of the resolution determined by the Crop/Selected and other Area to Render types except View.
