good question. i've never run across one. internally imlib2 is all 8bit anyway
per channel so it'd have to reduce colordepth to 8bit on load.

aah it returns a HANDLE - not a structure. that structure is internal and not
intended for public consumption at all. its private and you don't get access.
there are functions to GEt access to image parameters like
imlib_image_get_width() imlib_image_get_data_for_reading(); etc.

you just access and "copy" the parameters needed. notice that copying the pixel
data will be more overhead - extra memcopies and memory - you can just keep the
Imlib_Image handle in your structs and access the data as and when you need it.

that's the intention - you are not meant to find out! :)

in theory it could using cygwin - but in practise people have had problems. it
can be done as there are windows cygwin packages for imlib2, so someone has
compiled it - you may need to hack makefiiles etc. though.
