VoiceLessQ 7a7a05c7f0 Render: a picture too large for the media cache is kept smaller, not decoded on every render (#3665) ...

pixmap_for offered every decode to the media cache, and the cache
refuses an entry larger than its whole budget (128 MB, source bytes
included). A picture between that and the 512 MB decode budget (about
34 to 67 M pixels, which can be a small PNG) was decoded, thrown away
and decoded again each time a page holding it was drawn: while typing,
scrolling or zooming.

Such a picture is now averaged over square blocks of whole pixels down
to half the cache before it is stored. The pixels are premultiplied, so
edges keep their colour. Pictures the cache already held keep their
full size. Pages draw a picture scaled to its frame, so it lands in the
same place; a tiled page background now takes its tile size from the
picture's natural size instead of the pixmap's.

Measured with a 7000 x 7000 PNG on a page, dev profile (workspace
opt-level 1): every render took 0.27 to 0.28 s before. Now the first
takes 0.43 s and the next ones 0.3 to 0.5 ms. Peak RSS stays 399 MB,
the decode's own.
