This package illustrates an issue with irregular scaling of sphere markers (i.e. ellipsoids) when using the SPHERE_LIST marker type.
When running the provided launchfile, two identical sphere markers are published, one using SPHERE type and the other using SPHERE_LIST.
The outcome is that the SPHERE marker correctly renders an ellipsoid, while the SPHERE_LIST marker draws a regular sphere using the x value of the scale uniformly.
