I've recently developed a consistant and (relatively) simple method of generating font files that contain vector icons/graphics that can be displayed accurately as intended in themes. (For anyone wondering why, it's the only way of drawing re-colourable graphics with anti-aliasing.)
My question is, where do you think I should place these files? As they are technically a font, precedence would say they should be stored in the Fonts folder but a user selecting them from the Font menu would be left with an unreadable menu. On the other hand, placing them in the theme's folder in the wps directory would make some sense since these folders are used to store graphics, albeit intended for bitmaps. The only downside to this is that calling these using the font preloading tag, one has to point rockbox to the theme's folder from the font folder like "../wps/themefolder/file.fnt". None of this seems to be considered illegal by checkwps or the theme uploader.
My instincts say to place it in the wps directory instead of the font one, but I want to see what some other people's opinions are on this.
