f96ebb0986 Fix #66387: Stack overflow with imagefilltoborder 
The stack overflow is caused by the recursive algorithm in combination with a
very large negative coordinate passed to gdImageFillToBorder(). As there is
already a clipping for large positive coordinates to the width and height of
the image, it seems to be consequent to clip to zero also.

. imagescale
  . imageaffine
  . replace imagerotate with new generic and optimized new implementations
  . imagesetinterpolationmethod, to set the default interpolation to be
    used with the new functions
  . add imagepalettetotruecolor
