ScriptFu: Test: maintenance, fix tests broken by changes to Gimp, add tests.

Fix tests broken by changes to gimp_data, wilber.png=>gimp-logo.png

Uncomment failing tests whose issue was fixed.

Remove calls to deprecated functions.

Make more test files use v3 binding script-fu-use-v3

Compare floats relatively by epsilon.

Add some missing tests.

+## Test coverage
 
+You can get an approximate list of the internal PDB procedures tested:
+
+```
+>cd test/tests/PDB
+>find . -name "*.scm" -exec grep -o "gimp-[a-z\-]*" {} \; | sort | uniq
+```
+
+That is, for all files with suffix .scm in the PDB directory,
+grep for calls to the GIMP PDB which are like "gimp-", sort them, and get the unique names.
+
+We strive to not use the gimp- prefix on names in comments,
+exactly so this will find only actual calls.
