Press ALT+B in 3d window, draw a rect, and it becomes a clipping volume of 4 planes. You then can rotate the view anyway you like. Works for each 3d window individually. Disable it with another ALT+B press. Commit is huge because it had to change all selection code as well. The user-clipping planes are in 'eye space', the other clipping happens in projected 'viewport space'. Nice to notice is that the 'x=3200' convention (to denote a coordinate is clipped) now is a define. Define value is still a number though... but we now can get up to screens of 12000 pixels without issues! Known issue; here it refuses to draw the 'object centers' or Lamp icons within the clipping region. Can't find any reason for it... however, we might move to non-pixmaps for it anyway. Testing might reveil numerous issues, will be standby for it. Curious? Check this http://www.blender.org/bf/rt4.jpg
