In Rfc 24: GDAL Progressive Data Support it says that the metadata for a
driver will specify metadata item "DCAP_ASYNCIO" as yes if the driver
supports asynchronous IO. So, code like this should retrieve this option:
const char* s_asyncio = drv->GetMetadataItem("DCAP_ASYNCIO");

I am generating a geotiff from a WMS source. I can do so from either PNG
requests or JPEG requests. The PNG requests have better contrast but are
4x-5x as slow.
I would like to compare the PNG and JPEG request results for a
representative area and develop a contrast correction which I can apply to
