simple static multi-lingual titles instead of tracked titles

Instead of going the tracked title route, I settled on a simpler static title overlay using Blender VSE, because

• It's far less time-consuming
  
• Hindi text does not render well as a Blender text object
  

So,the workflow was:

• Create the title text in a document editor like Google Docs
• Take a screenshot of the black text on white background
• Invert to white text in black background on Gimp
• Overlay over "warped" video directly with opacity fading in from 0 to 0.5 over a second - OR -
  
• If overlaying over a fulldome clip, first "warp" the flat text to match the fulldome clip's curvature using the method in this old post.

In particular, after trial and error, the particulars seem to be:

• 36 point font size text to take screenshot
• stretch the text to make it square (halve the width)
• put the stretched screenshot at the bottom of a 4096x4096 transparent image
• make the screenshot even smaller if required, or use a larger transparent image
• merge down the layer if the filter doesn't act on the entire image
  
• use Gimp's Filter > Distorts > Polar co-ordinates with "Map backwards" checked (otherwise the text would be inverted left to right) and save as png preserving transparency (alpha channel).
