Improve memory leaks

ToDo.txt

-- recompute projections x and y min max values when zooming 
-- move icons to a system directory and not in the project
-- status bar with mouse coordinates using qt event and not matplotib one
-- nomad server restart ploty2 at during its starting
-- nomad gui closing shall closed plot windows
-- nomad gui starting shall restart previous display plot windows
-- recover size and position of plots and also states for grid, log , aspect ratio ....
-- Do offscreen for web plots and multiwindow plot
-- bring plot to front wait it was already open
-- send offscreen log image to log system
\ No newline at end of file
+* move icons to a system directory and not in the project
+
+* See possible using of CUDA acceleration
+
+* Multiclient options
+	- no offscreen log, webspy plots
+	- offscreen plots for spy and multiplot will be regenerated or taken form the nomad server computer
+	
+* ROI  
+
+* Cut windows
+
+* Bugs:
+	- Plot1D crash after several time using it, see core file, pb QT event
+	- Problem to pass from empty data to others 
+	- Problem close a plot take a time in cameo, so if restarting a new before finishing previous does not worked
