ExportOptionsJPEG both resolution and quality
We can export a JPEG using ExportOptionsJPEG() — but it allows to set only quality, not a resolution.
We can use ImageCaptureOptions() instead to set a resolution — but it won’t allow to set a quality, because seems to be designed for PNG (and substituting a format to JPG gives questionable results).
We need to be able to export JPEG images, controlling both quality and resolution, without using app.doScript() trick — it fails on Cyrillic folder names.

Options for exporting a document as a JPEG file, used with the exportFile method. There is no "resolution" property. And "ICC profile" too.
