Fixes various bugs in PS_continue_text(), PS_get_buffer(), PS_begin_page(), PS_arc(), PS_arcn(), and PS_set_border_style(). Adds support for BMP, TIFF, and GIF images. Adds a blind feature to PS_show_boxed(). Setting boxheight in PS_show_boxed() makes the box as large as needed.
PS_add_bookmarks() now works even with characters
in the bookmark text which are not allowed in
PostScript strings. PS_open_image() can read EPS
images from memory. Encoding vectors at position
363-365 were fixed. JPEG CMYK images can now be
read without segmentation faults. The character to
dissolve ligatures can be set through the
"ligaturedisolvechar" parameter. Entering
PS_PATH_SCOPE always starts a new PostScript path.
This fixes the clipping bug. Both grayscale and
RGB JPEG images can be read.
