Crop Factor Display takes actual crop into account

[Rewind]

It might be useful, if the 35mm equivalent crop factor display takes the actual crop factor of raw_rec crop box.
Let's say, I usually shoot at 1536xNNN on 650D, so my actual crop will be 1728/1536*1.6 = 1.8

In this case, if my lens at 28mm, the actual 35mm eq. will be 50, not 45.

Is it always defined from width?

Well, actually CF = DIAG35mm / DIAGsensor.
But when you are shooting at sinemascope ratios (like 2.4:1) it is feels like Width is the only really matters.
It's lke... when you make decisions of framing and lens choices while drawing the sketchboards, the width of the frame is the landmark or... reference.
So it will be fine enough to see 35mm eq. related to W35/Wactual ratio.

Or may be just give user the ability to fine-tune this multiply factor?
Then, for my example, I just put in the 1.8 and be happy.
