Timing & scale : 
     /home/bill/Projects/Stalin supported Hitler/animations - Howell/0_Howell animation timing.ods


*******************
20Apr2015  First try, after setting up translate & scale from image.


Build animation :
1. Gimp create new image 770*570 pixels, AND : 
   create 2nd transparent layer
   move transparent layer to bottom
2. Save as /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/02.1 Battle of Britain/1 Battle of Britain/Battle of Britain-000001.xcf
3. Duplicate blank image :  
   gimp menu -> video -> duplicate frames -> frames 1 to 1, N=483
4. a) gimp -> files -> open -> Image to move : 
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/02.1 Battle of Britain/1 Battle of Britain/1_MilAtlas- EuropeNW Battle of Britain Jul-Oct1940.jpg
   b) Close all other (irrelevant and confusing) gimp images
5.  Settings for animation layer
.
This is the FINAL list of settings & instructions.  See notes below for problems, fixes, experiments.

6A. From gimp window for the "blank" image : menu video -> move path 
   This brings up "Move Path" window
   a) should see "Current point: [1] of [1]
   b) source image layer : as above
   c) stepmode -> none, mode -> normal, handle -> center
   d) [x,y] -> [287	280]
   e) Scale & modify [width, height] -> [30%	30%], opacity -> 100, rotate -> 04], Layerstack 0 
6B. Click "Add point" button
   a) should see "Current point: [2] of [2]
   b) source image layer : as above
   c) stepmode -> none, mode -> normal, handle -> center
   d) [x,y] -> [-347	-51]  
   e) Scale & modify [width, height] -> [100%	100%], opacity -> 100, rotate -> 0
   f) Frame [from, to] = [1	484], Layerstack 0 
6C. If desired : "Anim Preview" button -> click it
   This brings up "Move path animated preview" window
   a) Object on empty frames -> set this radio button
   b) Scale preview -> 100 
   c) Framerate -> keep at 24
   d) Copy to buffer -> don't set
   e) Click "OK" button - this takes time!!! (monitor via "blank image" window)
6D. To save the "Move Path" result to the "blank image frames" : 
   a) In "Move Path" window, click "OK" - This takes time! - monitor in nemo file manager
   b) Check animation : in gimp window for the "blank" image :
      menu -> video -> Playback
.
First attempt - test settings for 1st try :
>>  OK, looks good!  Might zoom in more in the future...
