                     SDRTEXTANI_SLIDE};

// - SDRTEXTANI_BLINK:
//   Just blink.  Direction and Amount don't effect things.
//   Frequency delay: 0 = 0.5Hz (Delay = 250).
//   Count = number of blinks. (0 = forever)
//   start inside: sal_False = begin with the blinker off, sal_True  = begin with the blinker on
//   stop inside: sal_False = end with the blinker off, sal_True = end with the blinker on
//                (Only if count! = 0)
// - SDRTEXTANI_SCROLL:
//   Text just scrolls all the way through, and starts over when it is done.
//
//   Delay in ms: (except delay = 0 means 50ms (20Hz) default)
//   Count = number of passes (0 = go forever)
//   Direction: the direction to scroll
//   StartInside: sal_False = on the first pass, scroll the text in (not initially visible)
//                sal_True = on the first pass, the left part of the text is already visible
//                           in the scroll area before starting.
//   StopInside: sal_False = on the last pass, scroll the text all the way out.
//                sal_True = on the last pass, keep the right part of the text visible.
//                (Only if count! = 0)
//   Amount: Step size in logical units. Negative values = use Pixels instead
//           of logical units. If Amount = 0, then default to 1 Pixel.
// - SDRTEXTANI_ALTERNATE:
//   Like SDRTEXTANI_SCROLL, except don't scroll until all of the text is out,
//        but just until the last part is visible.  Then, change direction and
//        scroll the text the other way.
//   Count = number of passes (number of direction changes minus 1)
//        If count = 1, this is the same as SDRTEXTANI_SCROLL
//   Direction = the starting direction.
//   All Other Parameters: just like SDRTEXTANI_SCROLL
// - SDRTEXTANI_SLIDE:
//   Text will slide in to the original position.
//   -> same as SCROLL with StartInside = sal_False, StopInside = sal_True
//   and Count = 1 (Count = 0 is interpreted as count = 1).
//   For each count > 1, the text, will be slid out backwards
//   (much like ALTERNATE) and then slid back in again.
//   StopInside is not evaluated, because inside is always stopped.
//   StartInside is not evaluated, because outside is always started.
//   All other parameters are like SDRTEXTANI_SCROLL
// StartInside, StopInside: When sal_True, the starting / final position
//   of the text depends on the anchor of the drawing object.  This
//   corresponds to the position of the text in normal Paint (without scrolling).
