* New upstream stable branch snapshot.
  - Includes all the previous cherry-picked fixes
  - Fix crash when imgsvg is loaded, due to missing symbol 
    (decor_apply_gravity from libdecoration). (LP: #956986)
  - Fix multiple window placement bugs (LP: #974242) (LP: #976032)
  - Fix window handle leak causing gradual degradation in desktop 
    performance (LP: #1050610)
  - Some decoration pixmaps get leaked on window resize, due to race 
    conditions between gtk-window-decorator and the decor plugin.
    (LP: #1057263)
  - Avoid a NULL dereference and give a useful error message instead.
    (LP: #944653)
  - Fix leakage of destroyed_pixmaps_table, containing pointers to freed 
    decor_t's which could result in a freed GHashTable being passed into 
    g_hash_table_remove and causing a crash. (LP: #1060171)
* debian/patches/compiz-package-gles2.patch:
  - Drop the NEWS file, update decor.cpp part to build with new upstream
    code.
* debian/patches/revert_fix_933776_955035.patch:
  - Cherry-pick the revert from upstream since the bug fix is not 
    suitable for SRU as is
* debian/patches/revert_fix_994841.patch:
  - Cherry-pick also this revert as non-SRU material, not relevant 
    to users
* debian/libdecoration0.symbols:
  - Update with latest symbols
