This update for fontforge, ghostscript-fonts, ttf-converter, xorg-x11-fonts fixes the following issues:

Changes in fontforge:

- Support transforming bitmap glyphs from python. (bsc#1169444)
- Allow python-Sphinx >= 3

Changes in ttf-converter:

- Update from version 1.0 to version 1.0.6:
* ftdump is now shipped additionally as new dependency for ttf-converter
* Standardize output when converting vector and bitmap fonts
* Add more subfamilies fixes (bsc#1169444)
* Add --family and --subfamily arguments to force values on those fields
* Add parameters to fix glyph unicode values
--fix-glyph-unicode : Try to fix unicode points and glyph names
based on glyph names containing hexadecimal codes (like
"$0C00", "char12345" or "uni004F")

--replace-unicode-values: When passed 2 comma separated numbers
a,b the glyph with an unicode value of a is replaced with the
unicode value b. Can be used more than once.

--shift-unicode-values: When passed 3 comma separated numbers
a,b,c this shifts the unicode values of glyphs between a and b
(both included) by adding c. Can be used more than once.
* Add --bitmapTransform parameter to transform bitmap glyphs. (bsc#1169444)
When used, all glyphs are modified with the transformation function and
values passed as parameters. The parameter has three values separated by
commas: fliph|flipv|rotate90cw|rotate90ccw|rotate180|skew|transmove,xoff,yoff
* Add support to convert bitmap fonts (bsc#1169444)
* Rename MediumItalic subfamily to Medium Italic
* Show some more information when removing duplicated glyphs
* Add a --force-monospaced argument instead of hardcoding font names
* Convert `BoldCond` subfamily to `Bold Condensed`
* Fixes for Monospaced fonts and force the Nimbus Mono L font to be Monospaced. (bsc#1169444 #c41)
* Add a --version argument
* Fix subfamily names so the converted font's subfamily match the original ones. (bsc#1169444 #c41)

Changes in xorg-x11-fonts:

- Use ttf-converter 1.0.6 to build an Italic version of cu12.pcf.gz in the converted subpackage
- Include the subfamily in the filename of converted fonts
- Use ttf-converter's new bitmap font support to convert Schumacher Clean and Schumacher Clean Wide (bsc#1169444 #c41)
- Replace some unicode values in cu-pua12.pcf.gz to fix them
- Shift some unicode values in arabic24.pcf.gz and cuarabic12.pcf.gz so glyphs
don't pretend to be latin characters when they're not.
- Don't distribute converted fonts with wrong unicode values in their glyphs. (bsc#1169444)
Bitstream-Charter-*.otb, Cursor.ttf,Sun-OPEN-LOOK-*.otb, MUTT-ClearlyU-Devangari-Extra-Regular,
MUTT-ClearlyU-Ligature-Wide-Regular, and MUTT-ClearlyU-Devanagari-Regular

Changes in ghostscript-fonts:

- Force the converted Nimbus Mono font to be monospaced. (bsc#1169444 #c41)
Use the --force-monospaced argument of ttf-converter 1.0.3
