ESP Ghostscript 8.15.1

ESP Ghostscript 8.15.1 is stable release based on GPL Ghostscript 8.15 and includes an enhanced configure script, the CUPS raster driver, many GPL drivers, support for dynamically loaded drivers (currently implemented for the X11 driver), and several GPL Ghostscript bug fixes. The new release also fixes all of the reported STRs from ESP Ghostscript 7.07.x.

Changes in 8.15.1:

	- The shared X11 driver was not built with the correct
	  linker command (CCLD instead of CC_SHARED) (STR #1255)
	- The opvp driver incorrectly assumed that CODESET was
	  supported on all platforms that supported iconv (STR
	  #1247)
	- Updated the iconv checks so they work on more platforms
	  (STR #1154)
	- Added support in the "cups" driver for the
	  CUPS_CSPACE_RGBW colorspace (new in MacOS X 10.4 and
	  CUPS 1.2)
	- Added "SET RENDERMODE=..." PJL command to header of the
	  output of the "pxlmono" and "pxlcolor" drivers, this
	  way color laser printers get correctly switched between
	  grayscale and color mode and are this way often four
	  times faster in grayscale (Thanks to Jonathan Kamens,
	  jik at kamens dot brookline dot ma dot us, for this
	  fix).
	- Corrected Legal paper size definition for the "pxlmono"
	  and  "pxlcolor" drivers (Thanks to Jonathan Kamens, jik
	  at kamens  dot brookline dot ma dot us, for this fix).
	- Added some missing "$(install_prefix)"in the install
	  procedure of the extra files for "pcl3" driver.
	- The lips4 driver used a small string buffer to hold the
	  output resolution, which would cause a buffer overflow
	  for resolutions > 99 (STR #1241).
