annotate src/shape_rect.c @ 221:ad4f8a956505
Implement a workaround for the button class. However, this won't solve all issues. We can use this as example to fix the mouse out event issue. When we move the curosr over the text inside the button. The upper layer group will receive MOUSE_OUT events. This is absolute incorrect.
