static RotatedTextItem_t *	XRotCreateTextItem (Display dpy, XFontStruct font, float angle, char *text, int align)
	Create a rotated text item. More...

static void	XRotAddToLinkedList (Display dpy, RotatedTextItem_t item)
	Adds a text item to the end of the cache, removing as many items from the front as required to keep cache size below limit. More...
