[feature request] Add "Decimal" to the option "View" > "Label Glyph By"

[rodrigomorales1]

When you open an issue for a change/improvement/feature request:

Let me explain the context: I'm performing some experiments with regards to LaTeX compilers and fonts. In one of those experiments, I have had to find characters in a given font given their decimal notation. Currently, fontforge displays the decimal notation for each character in the top left corner (see screenshot below). However, there's no option for displaying the decimal notation as the label for each character, there's only "Encoding Hex". I'm aware that converting hexadecimal number to a decimal number is a trival task for some people, but at the moment, I cannot quickly convert hexadecimal to decimal in my mind. Therefore, it would be more convenient for me to see the decimal notation as the label for each character.

I suggest adding "Decimal" as an option "View" > "Label Glyph By", so that the number that is shown in the top left corner is shown at the top of each character.

• A description of the problem you're trying to solve, including why you think this is a problem: Some users, such as me, might be find it more convenient to read decimal numbers instead of hexadecimal numbers as the label for each character. Currently, the user needs to click on a character in order to see the decimal notation in the top left corner. By providing the option "Decimal" for the labels, the user can see the decimal code for all characters in the window when desired.

• If the feature changes current behavior, reasons why your solution is better: My solution doesn't involve changing current behavior, it involves adding a new option in order to suit some users' needs that weren't satisfied before.
