[New-bugs-announce] [issue41851] tkinter: add font neg and equal methods

[E. Paine]

New submission from E. Paine <paineelisha at gmail.com>:

I think it would be helpful to add these methods to the tkinter font class.

Starting with the equal method, I have found it very useful to be able to compare tkinter fonts based on their value rather than just name. I used this, for example, in #28694 to ensure the -font attribute had been changed correctly (though there I compared each of the attributes explicitly rather than using `.actual()` as I have in this patch).

The neg method, I think, would be very useful to allow easy conversion between points and pixels. For example:

points = Font(size=16)
pixels = -points
