[QGIS-Developer] Zoom to Scale Plugin - Should we include it on qgis.org?

[C Hamilton]

Richard,

Thanks for that information. I meant plugins.qgis.org. From the URL you
sent it looks like it has many of the components and it gives me ideas for
EPSG:4326.

Unless someone else is working on this I will submit a plugin after I see
if I can make it work with other CRS tile caches.

Thanks,

Calvin
