 Hi all,

 I'm pleased to announce that the new GIMP developer wiki
 has found its way home and is reachable as wiki.gimp.org now.
 That's great! I have removed 'GIMP' from the roadmap title now since the
 domain itself has enough GIMP-weight, the roadmap can now be found at:

 http://wiki.gimp.org/index.php/Roadmap


 Thanks a lot to LightningIsMyName and Alexia for starting,
 hosting, and taking care of the wiki.
 Indeed, thank you Alexia and LightningIsMyName.

/ Martin
And my thanks to the two of you as well - the organization and content of the 
wiki gives me some confidence I might be able to contribute in future :)

 say you got a slider going from 1 to 1000. then divide the slider
 range (in pixels) in 3 equal parts, so that each handles a decade:

 |--   1–10   --|--  10–100  --|-- 100–1000 --|

 within each third the increase/decrease of value is linear.
This looks neat -- OTOH as tablets get more multitouch the current
trend seems to be touch speed controls rate of change nonlinearly.
Mouse tracking could execute this way. Looks hard, tho :-)

Re: [Gimp-developer] Looking for guidance on implementing a plugin

 I looked at that one and they simply create a new image with a scaled
 version of the active layer, which is sub-optimal from a UI
 perspective (the plugin registers under the Image menu, but only
 scales one layer, and ends up create a new image).

 The built-in scaling options are:
   Image-Scale Image which scales all the layers, layer masks, channels
 (including the active selection) and paths of the image, not just the
 active layer
   Layer-Scale Layer which scales the active layer only but does not
 change the image canvas size or scale the associated layer mask (is
 that a reasonable behavior?).


 Thinking about it, I guess my initial question really had two parts:
  From a UI perspective:
   - should an action like scaling create a new image? (I'm leaning towards no)
   - should an action like scaling scale all layers, masks, channels
 and paths of an image if it is the image menu (otherwise in the layer
 menu)? (I'm leaning towards yes)
   - should an action like scaling a layer also scale an associated
 layer mask? (yes?)
   - with 2.8 having layer groups, will any of this have to change?

 From my (quite naive) perspective, it feels like a layer mask should 
scale with the layer in the Layer menu.  I would expect a layer group to 
scale all layers (and their masks as well, for those layers in the group 
with an associated mask) in the group proportionately - which implies a 
Layer Group-Scale menu item.
  From a programming perspective:
   - Assuming I have decided my plugin will rescale a layer only (i.e.
 from the user's perspective the active layer gets scaled) is it better
 to create a new drawable to contain the scaled image and insert it in
 the layer stack and delete the initial layer, or better to use
 gimp_pixel_rgn_init to grab the pixels from the source layer, then
 change the layer boundary size and and use gimp_pixel_rgn_init to
 create a second pixel region as an output buffer pointing to the newly
 sized drawable?
