Multi-line and tabbed strings drawn with a scaleMultiplier != 1 overlapped
or misaligned because the font code advanced newlines and tabs by the
unscaled font height/tab width -- most visible in FRED's viewport labels
now that they honor an adjustable font scale.
Scale the newline and tab advance in both the rendering and measurement
paths of each backend: the NVG path (gr_string and NVGFont::getStringSize)
and the VFNT path (gr_string_old and VFNTFont::getStringSize), which also
gains tab handling. The tab width is hoisted onto the shared FSFont base
so both backends share it.
While here, pass the FSFont wrapper to gr_string_old instead of a bag of
scalars, make its font pointer const, and consolidate the
get_char_width_old externs into a single declaration in font_internal.h.

Add coverity[GLOBAL_INIT_ORDER] annotations to ~50 global variables
across 27 files. These were all analyzed and confirmed safe:
- ~48 OptionBuilder::finish() globals use a Meyers singleton
(OptionsManager::instance()), which guarantees safe init order.
Destruction is also safe due to shared_ptr ref-counting.
- 6 default-constructed container globals (vectors, maps) have no
cross-TU dependencies at construction or destruction time.

* Add method to get a font's font family
* nullptr
* add more safety checks
* pass font data instead of font data members
* return an empty string instead of unknown
* allow VFNTs to auto scale and disallow auto scaling in FRED
* fix shadowing
* Update FSFont.cpp
* don't code from your phone, mjn
* refactor to use one central method
* Add option to set a font size multiplier for ttf fonts
* remove the option if we have no scaling fonts
* Clang the conquerer strikes again
* Update XSTRs
* clang
* Clarify comments
1. Stores the filename from the table Parser into the font struct so we can lookup fonts via their filename.
2. Allow "+Special Character Font:" to specify the first entry with the same filename's special character index for their own special character index, provide a default if not, and allow the moddert to specify them manually, but do not override already recorded values if the default is picked in order to protect retail behavior.
3. Vectorize Special Character Indexes, so that we don't have a table limit that will randomly crash FSO based on what table you happened to write! Woohoo!
This allows to use standard TrueType Fonts for text rendering in FSO. It uses the NanoVG library which provides the ability of drawing 2D shapes. This library is used for most 2D operations now and can also be used directly by using the PathRenderer class.
