 * qglobal.h (Qt header) typedefs INT32 to int (always a 32-bit signed type on

 * of the libjpeg API for more than 20 years, we can't remove it, but we do not

 * change these macros, rebuild libjpeg, and link their application statically

 * severe restrictions involved (cjpeg and djpeg no longer worked properly,
 * compressing/decompressing RGB JPEGs no longer worked properly, and the color
 * quantizer wouldn't work with pixel sizes other than 3.)  Further, since all
 * of the O/S-supplied versions of libjpeg were built with the default values
 * of RGB_RED, RGB_GREEN, RGB_BLUE, and RGB_PIXELSIZE, many applications have

 * The libjpeg-turbo colorspace extensions provide a much cleaner way of
 * compressing from/decompressing to buffers with arbitrary component orders
 * and pixel sizes.  Thus, we do not support changing the values of RGB_RED,
 * RGB_GREEN, RGB_BLUE, or RGB_PIXELSIZE.  In addition to the restrictions
