Typedefs
typedef struct RotatedTextItemTemplate_t	RotatedTextItem_t

Functions
static XImage *	MakeXImage (Display *dpy, int w, int h)

	A front end to XRotPaintAlignedString: -no alignment, paints background.

int	XRotDrawString (Display dpy, XFontStruct font, float angle, Drawable drawable, GC gc, int x, int y, char *str)
	A front end to XRotPaintAlignedString: -no alignment, no background.

static void	XRotFreeTextItem (Display dpy, RotatedTextItem_t item)
	Free the resources used by a text item.

static XImage *	XRotMagnifyImage (Display dpy, XImage ximage)
	Magnify an XImage using bilinear interpolation.

static int	XRotPaintAlignedString (Display dpy, XFontStruct font, float angle, Drawable drawable, GC gc, int x, int y, char *text, int align, int bg)
	Aligns and paints a rotated string.

static RotatedTextItem_t *	XRotRetrieveFromCache (Display dpy, XFontStruct font, float angle, char *text, int align)
	Query cache for a match with this font/text/angle/alignment request, otherwise arrange for its creation.

void	XRotSetBoundingBoxPad (int p)
	Set the padding used when calculating bounding boxes.

void	XRotSetMagnification (float m)
	Set the font magnification factor for all subsequent operations.

XPoint *	XRotTextExtents (Display , XFontStruct font, float angle, int x, int y, char *text, int align)
	Calculate the bounding box some text will have when painted.

float	XRotVersion (char *str, int n)
	Return version/copyright information.
