...in both the core and libgimp.
Images now know what the default mode for new layers is:
- NORMAL for empty images
- NORMAL for images with any non-legacy layer
- NORMAL_LEGAVY for images with only legacy layers
This changes behavior when layers are created from the UI, but *also*
when created by plug-ins (yes there is a compat issue here):
- Most (all?) single-layer file importers now create NORMAL layers
- Screenshot, Webpage etc also create NORMAL layers
Scripts that create images from scratch (logos etc) should not be
affected because they usually have NORMAL_LEGACY hardcoded.
3rd party plug-ins and scripts will also behave old-style unless they
get ported to gimp_image_get_default_new_layer_mode().
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
...in the export dialog
Read back timestamps into layer names. Adds the exact duration to the
layer names. Previously, they were not reloaded correctly.
- handle all sorts of image types, gegl_buffer_get() will convert to u8
- specify GIMP_EXPORT_CAN_HANDLE_LAYERS_AS_ANIMATION
- modify the export duplicate, not the original image
- fix handling of the drawable type and only save "R'G'B'A u8"
or "R'G'B' u8", fixes bug 770664.
- completely redo run(SAVE_PROC) to deal with export correctly
- turn global variables into the standard SAVE_PROC, PLUG_IN_BINARY etc
defines
- simplify the save dialog
