drawing in the desktop program

i need a software to draw lines of different colors in my desktop. it must draw in multiple monitors. ## Deliverables the software must draw lines in the dektop, for those lines i must be able to select the color of the line(just 7 colors (red, green , yellow, pink, white, magenta, black). if i press ctrl key, the line that i am drawing must be perpendicular(horinzontal or vertical). when i am drawing the application that are running in my desktop must stay visible and not frozen. when i finish to draw a line it must be visible. if i select a line and press the right mouse key i must have a menu where i choose: 1- the colour of the line 4- line width (3 different width) 2-to delete the line 3-to duplicate(when i press that option it appears another line , with the same characteristics) those lines must be able to draw in several monitors (i have multi monitor , 2 different vga boards). there should be a delete all lines command, a transparency level for the lines a frozen command and exit program command. the frozen command is when i finnish to draw the lines and i want to continue to work with another programs . so the frozen command must allow to continue to work with other programs witout delet the lines. the lines must be allows on top (i just can change the transparency level) if i press the frozen command again then i am able to add and draw more lines. the exit command leaves the the program and delete all the lines.
