By the way, the default page cache size is 32 MB which strikes me a
quite generous. :-) So make sure to call
PageItem::setCacheSize(cacheSizeInByteAndPossibilyZero) before using the
document view... (Another memory usage problem is that the program will
always rendering whole pages and not just the visible parts, so even the
temporary buffers can be quite large at high resolutions and scale
factors and the cache will only be useful if is able to contain at least
one page (page width * page height * (dpi/27 * scale)^2 * depth).)
