[sane-devel] ESCL test

I finally got around to testing the new escl backend with my HP OfficeJet
It does appear to be supported on two ports, one encrypted:
device `escl:https://10.1.40.2:443' is a ESCL HP-OfficeJet-6978 SSL flatbed
device `escl:http://10.1.40.2:8080' is a ESCL HP-OfficeJet-6978 flatbed
Preview and higher resolution scans are OK.
However, there appears to be something squiffy about the geometry options.
I cannot get a full sheet scan.
This is what I get from scanimage as regards the available options:
Options specific to device `escl:https://10.1.40.2:443':
--mode Gray|Color [Gray]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 75|100|200|300|600|1200dpi 
Sets the resolution of the scanned image.
Request a preview-quality scan.
Request that all previews are done in monochrome mode. On a
three-pass scanner this cuts down the number of passes to one and
one-pass scanner, it reduces the memory requirements and scan-time
-l 0..0.0122375pel (in steps of 1.52588e-05) [0.000244141]
Top-left x position of scan area.
-t 0..0.0156708pel (in steps of 1.52588e-05) [0.000534058]
Top-left y position of scan area.
-x 0..0.0119934pel (in steps of 1.52588e-05) [0.0386658]
Width of scan-area.
-y 0..0.0151367pel (in steps of 1.52588e-05) [0.0529785]
Height of scan-area.
Using the current PPA from Rolf as of today, which is probably gonna be *git
