before this only active scene would be rendered with border. When do_render_fields_blur_3d() is finished, it'll modify render's display rect so it'll correspond bordered render result placed on black backgrund. Actual border is stored nowhere, which makes it only way to re-calculate disprect for all other renders used in compo based on source. Not so big deal actually. Also needed to modify Cycles a bit, because before this patch it used border settings from scene being rendered. Now made it so render data is passing to external engines. Using a property inside RenderEngine structure for this. Not best ever design for passing render data, but this would prevent API breakage. So now external engines could access engine.render to access active rendering settings. Reviewed by Brecht, thanks!
