Agreed. We should show all of the image in our preview.

No, definitely not. In fact, if I remember correctly, preview copies & rend=

|

the complete image. Options are:
|
|
|
|
* Just preview the active layer, out of context
|
|
* Copy the image, scale it down, and then render it. Cache the scaled-down=

|
|
thumbnail.
|
|
* Work on the QImage of the rendered image, and apply all filters on that -=
|
|
=2D=20
|
|
for preview, that may be accurate enough.
|
|
|

Note that we want a fast thumbnail preview for in the bird's eye box, too, =

in the variations dialog we need a whole bunch of previews. So I guess the=
|
|

|
|
requirements are:
|
|
|
|
* Frugal with memory
|
|
* Fast
|
|
* Filters should work on the preview image
|
|
* Zoomable, but initially the complete image/layer is shown
|
|
* Selectable: preview layer/preview image
|
|
|
|
I have a feeling that this may be hard to achieve...
