Currently I think the cursor hot spots are not considered when drawing the cursor at the specific coordinates. This results in some cursors being a bit of in the recorder compared to what you see on screen.

cursor_hot_x and
cursor_hot_y

are actually in the code and are being used at the the drawing step:

cairo_set_source_surface (cr,
  recorder->cursor_image,
  recorder->pointer_x - recorder->cursor_hot_x - recorder->area.x,
  recorder->pointer_y - recorder->cursor_hot_y - recorder->area.y);

However these values are never being set. Perhaps the "on_cursor_changed" routine that reads the current cursor image buffer should also read the current hot spot coordinates from the cursor?
