Hi,

Image support is required by darktable (RAW photos processing) as can be seen
in the following output, from runnind darktable -d opencl:

[opencl_init] opencl related configuration options:

[opencl_init] discarding device 0 `AMD OLAND' due to missing image support.
[opencl_init] no suitable devices found.
[opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.
[opencl_init] initial status of opencl enabled flag is OFF.

Not sure if anything else is needed to get OpenCL to work in darktable but it
would be very sweet to be able to get that with open source drivers.

Thanks,
Thomas
