Crash when picking color

When picking a color from a picture, PyDPainter crashed:

Looks like the mouse coordinates went outside the bounds of the canvas and caused the Surface get_at_mapped() call to fail.

Need to constrain mouse coordinates to canvas in config.get_mouse_pixel_pos().

Was able to recreate:

  • Press F11 to make full screen
  • Magnify the extreme lower-right corner of the screen
  • Zoom in or out to make the right and bottom edges have some gray color (off-canvas area)
  • Click on the color dot to get the dropper
  • Drag mouse around the lower right of the zoomed window
  • Crash when dragged past lower-right edge of zoomed window (off-canvas)
