Summary	0000599: Blur plugin "Alpha determines radius" problem
Description	The Blur plugin has an "Alpha determines radius" button which does something but it is not clear if it works correctly or even if it is worth having. There is a Mailing List thread about it dated Dec. 21, 2021 with the title of "Blur plugin: Alpha determines radius" by Igor Beghetto. At this time it is still in the code, but it may be commented out in the future until it is ascertained if it is useful. To see what it currently looks like, follow these steps: Step 1 - start Cinelarra and just wipe an area to drag the "Title" plugin to it and type in some words using a large size (such as 100) to see in Compositor. Step 2 - now drag the "Blur" plugin to that same area and bring up the menu; click the "Reset" button. Look in the Compositor to see what it looks like and then Check the "Alpha determines radius" box and you can clearly see a difference.
