Ghostscript now reduces memory usage when processing PDF files that use 
transparency and output is to display devices such as Windows display or x11 
(i.e. devices that are strictly full framebuffer devices), and to high level 
vector devices that cannot reproduce the PDF transparency model, such as the 
ps2write device or pdfwrite when 'flattening' to PDF 1.3 or earlier (-
dCompatibilityLevel=1.3). This uses banding (clist) files to render the 
transparent areas in bands to reduce memory use, and unlike the existing page 
level banding, this is hidden from the target device.
