Zoom offset adjustment for one imagery template

Description

ZOOM_OFFSET global parameter allows to select hi- or low-res imagery for zoom levels in JOSM.
It works great for bitmap/photo resources, but has side-effect for services with text info rendered - name labels, building numbering etc. Text is rendered from vector sources for given resolution on server side and re-scaling it in JOSM gives ugly results.

With low-res global setting all texts are blurred and shifted from original location, and with hi-res zoom_offset they are too small and unreadable.

There should be new zoom_offset_adjustment parameter defined per imagery source to change/modify global setting for selected layer: ZOOM_OFFSET=+2, ZOOM_OFFSET_ADJUSTMENT=-2 should give zoom offset =0 for specific layer.

Or different approach:
Add zoom_offset parameter to imagery source overwriting global setting.
