Fix cursor freezes in GAL

Launching right click context menu overrides the cursor position, so all
actions executed by the tools will be performed in the right click
position. It created an issue, as the overridden cursor settings were
saved into wrong context if there was another tool activated in the
meantime.

Current implementation saves cursor settings for all tools and restores
them once the right click context menu disappears.
