[x3d-public] Where have all the flowers gone? John status.

[Holger Seelig]

Attached flower.zip with shaders updated to WebGL2 also have a look at https://webgl2fundamentals.org/webgl/lessons/webgl1-to-webgl2.html <https://webgl2fundamentals.org/webgl/lessons/webgl1-to-webgl2.html> how to WebGL to WebGL2.
Also updated flowerproto.json. ComposedCubeMap fields are actually back, front, … not backTexture, frontTexture, …

Best regards,
Holger
