[x3d-public] X3DCanvas vs x3d-canvas, X_ITE

[Holger Seelig]

With version 6.0.0, X_ITE uses the new element name <x3d-canvas>, lowercase and with dash. Because X_ITE uses the Custom Element API from JavaScript now. This has the advantages that the element can be created with document.createElement, and is then immediately ready to use :). Other advantage is that the CSS file must not be included anymore.

For compatibility the old name can still be used, but we encourage all users to update to the new tag name.

Best regards,
Holger
