Use custom VF axes for CRT bleed and scanlines

[felipesanches]

it is very cool that you've got variation axes for CRT bleed and scanlines. I just disagree to the use of wdth and wght for those variations

I agree. Any reservations against using custom axes regarding the prospective release on Google Fonts, @davelab6?

The problem with the custom axes is that they need to be registered, and the process is quite long and the font can be pending for weeks/month. I would advise to build a case in this issue: google/fonts#3425 with images so all (like in: google/fonts#2849)

First I thought you meant the axes need to go through the OpenType specification axis registration process and was prepared to give up ;) But now I see Google has its own registry.

I changed the axis names in the fonts and added proposals for the new axes to be included in the Google Fonts Axis Registry: google/fonts#3697, google/fonts#3699
