在lite_config.h里面定义了默认的字体:
#define DEFAULT_FONT_SYSTEM                     "vera"
在创建一些控件如label,button的时候要取得字体,如果没有字体的话当然也就无法运行了.默认的安装路径是/usr/local/share/fonts/truetype下.

当然除了定义使用什么字体,也可以定义字体的类型,在font.c中定义了四种类型:
static char* font_styles_global[4] = {
     "", "bd", "i", "bi"
};
分别是正常,bold, italic, bold italic.
在webkitdfb中初始化就用到了bd.

struct _LiteFont {
     int            refs;
     char          *file;
     int            size;
     IDirectFBFont *font;
     DFBFontAttributes attr;


     LiteFont      *next;
     LiteFont      *prev;
};

static LiteFont        *fonts       = NULL;
在文件开始处定义了结构体LiteFont全局变量fonts.如果现在的程序中使用了一种新的字体就增加在这个双向链表的头部.如果现在使用的这种字体已经在链表中有了就对引用值加１就可以了.
