Hi all
I made a patch to prevent E to show the mouse cursor. This is useful when
you're using a touchscreen.
Basically I created one more e_config field (show_cursor). When show_cursor
== 0, the pointer's evas canvas is freed and the functions to resize and set
type are prevented to run.
This solution is better than draw a transparent cursor...
If you try to hide the cursor and a "X" format cursor appear, recompile the
X with "--enable-null-root-cursor".
