I'll double check if that is indeed correct.
othoh if you have a 'staging' branch for these.. I may just try to
build _that_ and report.

2/ it may not be possible to address all these in one pass...
The problem I have not yet figured-out entirely is how properly deal
with size of the bitmap as expressed in 'point'
and size of he bitmap as expressed in 'pixel'....
and some bmp are 'resource' and other are 'generated at runtime (like
preview)... these pose a different set of problems.
3/ macosx magically deal with the scaling by default.. in fact _not_
making it do that for bitmap turned out to be something I have not
figured out yet...
/me has bitten the bullet and bought a couple of book about coca and
quartz programming.. with the hope to gain enough understanding of the
beast to be able to move vcl toward an api that would support some
control over these...
