Axis should have option to have a fixed orientation

[pzwang]

Right now axes determine the orientation of the "In" vector based on which side of the plot they're on. For axis locations of "min" or "max", that's OK, but when a plot has a fixed position in dataspace, then it should be able to have a fixed orientation, i.e. tick labels are always above/below or always left/right of the axis.

@bryevdv I don't know the guts of BokehJS well enough, but I'm pretty sure this is no longer applicable. Am I correct in thinking so?

[bryevdv]

Yes and no... It's no longer applicable because the ability to position axes at fixed data space coordinates is currently removed. But, it should be added back at some point when we can figure out how to make it work.

What problem exactly needs to be figured out?

[bryevdv]

There's a tension with the current layout system capabilities and what can be spelled.

I actually don't think this will be terrible to implement at this point but there are too many bugs left to fix for 0.12.6, moving to next milestone
