Roadmaps here, surveys there, when can we expect to see a true 64 bit 
native Delphi compiler to write code for 64 bit XP or Vista? When too 
can we expect support for all the recent flavours of SSE implemented 
directly in the compiler?

Speaking for the few  (?) of us who don't write "business" software 
or decorative stuff for the Web but write for those who do serious 
number crunching on large images only to have 32 bit Windows collapse 
with "out of resources" exceptions just like 16 bit Windows used to 
do with today's digital images, it's been a long and painful wait.

A work-around like using memory mapped files and copying memory from 
a small bitmap with a canvas to which one can write symbols or text 
to a very large one as a memory mapped file, given the limitations of 
492MB in XP and 650MB in WinServer2003 (see Windows Internals 4th 
Edition, pp. 401-413 for all the gory details) is a messy kludge, 
although I currently have to do this on the 20k x 20k color digital 
maps which are now supplied by a number of government mapping 
agencies here in Europe.

By large images I mean things coming from photogrammetric digital 
mapping cameras like those available from 
http://gi.leica-geosystems.com/LGISub1x2x0.aspx or 
http://www.intergraph.com/dmc/default.asp or alternatively, to see 
what I mean, download 4 full Landsat 7 tiles from near the Equator, 
use the utilities available on the web site below to convert each 
mrsid image to Tiff at full scale and then try to write some text to 
them after loading four tiles to get the overlaps.

Or am I missing something in versions of Delphi later than 7?
