The details

Resolves

No reported issue.

Proposed Changes

Removing the empty namespace objects that use to contain the original block colour constants.

Reason for Changes

These namespaces use to contain the original block hue constants, but were deprecated (via comment, except for procedures) over a year ago. With the removal of those constants, the declarations were creating empty, unused objects.

References to old block constants were failing silently because the empty object existed.

Test Coverage

Rebuilt compressed files and ran graph demo, which referred to the old constants (#1790).

With this change, the demo now throws:

index.html:225 Uncaught TypeError: Cannot read property 'HUE' of undefined
