Michael Natterer 1d2c015dcf app: fix modifiers being stuck in transform tools 
When the active modifier mode is GIMP_TOOL_ACTIVE_MODIFIERS_SAME (the
tool does not want to distinguish between modifier states depending
on whether or not the first mouse button down), we need to make sure
these states are in sync in GimpTool's bookkeeping, and we must not
generate synthetic modifier releases when the mouse button is
released.
