the "tool" implementation. Previously, the "tool" implementation
would overwrite the button bindings for the mouse. The problem
with that is that if the user customizes one or more of the
bindings, such as using the mouse wheel for zooming instead of
panning, then the custom macro gets obliterated when the tool
changes. The reimplementation creates multiple macro sets which
are unique to each tool. The "enable_tools" function sets up
the initial unique default bindings for each tool. The user
can then customize the bindings for any tool, and the
implementation no longer requires the constant changing of key
bindings. Note that the new implementation is slightly less
efficient because the macro tables are found by string hash
based on the name of the tool or client type, not the integer
client ID. The reduction in efficiency is balanced by the
increased flexibility of the macros.
