Subject: [PATCH] Bugfix - Long Keyframes:

In a A___B|---|B situation created by duplicating the B keyframe, the long keyframe between the 'B' keyframes was not showing up until the A keyframe was already duplicated. Reverting the 'optimisation' applied there (i.e. searching from last block, as that's where most blocks would be added)


Also removed some unused lines from gpencil.c
