Attached is a zipfile with some png icons.
I need the following changes made to them:
1) widthmm, clearscreen, SaveScreenshot should all use the same rectangle to represent the screen, this rectangle should be as large as possible
2) widthmm should have a transparent background and the middle building should be deleted and the remaining two made larger and clearer
3) gridon should have a 3 by 3 grids of large dots (the dots should be as large as possible)
4) gridwidthmm should have the same 3 by 3 grid of dots as gridon, but with the arrow.
5) clearmesh should be changed to be like createmesh only with the eraser from clear screen over the top and middle of the mesh.
6) redo the 2 icons with just text in them so they look good and the font is bigger (the letters can overlap a little if that looks good)
Icons can be 19mmx19mm to 50mmx50mm larger is preferred. They get displayed at about 30x30 so make sure they look ok at that resolution.
Very important: All icons need to have a transparent background.
