--- Comment #1 from Armin Le Grand <Ar...@me.com> ---
ALG: Please check with the soon released AOO401; I did some changes and a short
comparison on my machine showed 7s load compared to 10s, immediate rotation
possible and much faster zooming/scrolling.
Load time could still be improved, but would need deeper changes then, internal
infos: the jpeg loader imports to an own buffer, copied to (class) Bitmap's
internal buffer, GDI system dependent/independent created, then GDI+ created.
Parts are system-dependent, parts are not (we support not just win, so e.g. not
possible to use MS's jpeg importer to get GDI+ object directly). A lot of space
for improvements...
