There should be no visible change. The difference is mostly on how we
changed the rounding to handle the conversion from color space to the
new linear space of the attribute colors.
To convert the materials in icon_geom.blend I used:
```
import bpy
from mathutils import Color
def convert_material(material):
if not material.use_nodes:
return
if not material.node_tree:
return
node_tree = material.node_tree
for node in node_tree.nodes:
if node.type != 'RGB':
continue
color_original = node.outputs[0].default_value
color_new = Color(color_original[:3]).from_srgb_to_scene_linear()
color = (*color_new, color_original[3])
node.outputs[0].default_value = color
def main():
for material in bpy.data.materials:
convert_material(material)
main()
```
This is fundamentally different from Shrink/Fatten for meshes, because the control points are not moved, only the radius.
