8 bytes is the minimum header size for DMX, so for one byte of sample data it has to be 9 bytes.
This was causing access to invalid memory when trying to read the header of something too short.
For other file formats this is of no concern because none has a header this short.
In the old system it just loaded the font a second time, but with the folder based setup there is no file named CONFONT anymore so it needs to be dealt with explicitly.
This was already far too generous and caused space problems, but with localization these became a lot worse, so now it will try to allocate at least 640 virtual pixels for the menu width and only go below that for small resolution ranges where the smaller value would result in too small text.
This function was written for already validated UTF-8 but not for text that can be mixed with ISO-8859-1.
To handle that properly it needs to do a bit more validation to avoid mangling its output and instead reject invalid input.
Now a localization mod can disable the graphics patches containing text entirely so that it can properly localize the text based menu variant.
If this flag gets set in MAPINFO, it will override all user settings.
These were pixel format conversion routines used in the D3D backend. Nothing in here is needed anymore - the FBitmap class offers much of the functionality covered here in a far more concise and approachable manner.
The usedcolors array which counts the number of pixels in a given color in a font used bytes as storage, so any color that just happened to have a count that is a multiple of 256 the color was considered not present.
* added a CVAR that sets how localizable graphics need to be dealt with.
* pass the substitution string to OkForLocalization so that proper checks can be performed.
* increased item spacing on Doom's list menus to 18 from 16 pixels, because otherwise the diacritic letters would not fit. 20 would have been more ideal but 18 was the limit without compromising its visual style
* added a second text-only main menu because here the spacing cannot be changed. Doing so would render any single-patch main menu non-functional. So here the rules are that if substitution takes place, it will swap out the entire menu class.
* fixed some issues with the summary screen's "entering" and "finished" graphics.
