pdb: normalize the compat motion blurs' angles to -180..180
app, plug-ins: move everything from Render->Clouds to the new Render->Noise

because that's what they are and what most menu labels in there says.
Keep the "Clouds" menu around for 3rd party plug-ins, not sure if it's
right to auto-map it to "Noise" automatically.
app: use 1 and 15 increments for GEGL properties with the unit "degree"
app: let GEGL properties with unit "degree" wrap around

if their total range spans 360 degrees.
app: only auto-link GEGL properties of unit "pixel-distance"
app: put the chain on all adjacent "x" and "y" GEGL properties

regardless of their unit. This heuristic works surprisingly well.
script-fu: fix FOO-BUCKET-FILL compat enum value constants
app: gegl:noise-cell -> gegl:cell-noise
app: use plain spinbuttons for random seed GEGL properties
libgimp, script-fu: remove GIMP 1.2 (sic) compat defines

which we wanted to remove in the "next development cycle" after 2.0,
which would have been in 2.1.x.
devel-docs: no need any longer to ignore gimpcompat.h, it's gone
Bug 729068 - Gimp windows state is lost when closed from the window manager

Set gtk_window_set_skip_taskbar_hint() to FALSE for all dock windows.
libgimpwidgets, app: add gdk_screen_get_monitor_workarea()

to the gimp3migration hack and use it where appropriate, so in the
gtk3-port branch windows will not overlap with docks, panels etc.
build/win: Upgrade poppler to 0.26.0
build/win: Upgrade gdb to 7.7.1
icons, libgimpwidgets: get rid of compiled-in icons

Register the stock icons with icon-name sources instead of inline
pixbuf sources so they simply use the icon theme icons insatead of
duplicating them.
app: use step, page and digits as provided by gegl pspecs
app: minor cosmetic cleanup in the GEGL property code
plug-ins, pdb: remove the deinterlace plug-in and add a PDB compat proc
app: ref/unref layer->fs.drawable in gimp_layer_set_floating_sel_drawable()

It always felt wrong not to ref it, but now it started crashing. Dunno
what exactly has changed, but for example the "Weave" script was
triggering it.
