again so as not to break old SVG-Edit which fail at *presence* of
`namespace` (fixes#274)
- Known regression: Remove Openclipart as its site's now setting of
`X-Frame-Options` to `"sameorigin"` makes it unusable on our end
for our cross-origin uses
- Forward compatibility enhancement: For IAN image library, add
`svgedit=3` param to URL so that it can keep using old API for
SVG-Edit versions before 3, while conditionally using new object-based
API now (and if we switch exclusively to the object-based API in the
future, this site will continue to work)
- Docs: Add "Forward compatibility enhancement" to list
- Fix: Ensure all apostrophes are escaped for `toXml` utility
- Fix: Avoid error if `URL` is not defined
- Fix (jPicker): Precision argument had not been passed in previously
- Fix (Star extension): Minor: Avoid erring if `inradius` is `NaN`
- Refactoring: Avoid passing unused arguments, setting unused variables,
and making unnecessary checks; avoid useless call to `createSVGMatrix`
- Linting (LGTM): Add `lgtm.yml` file (still some remaining items flagged
but hoping for in-code flagging)
- Docs: Contributing file
