🎀 Detailed Description 🎀

so basically it's a state machine for rectangle selections. periodt. 🍓

here's the whole vibe, mouse edition first:

• Pressing QwtEventPattern::MouseSelect1 starts the selection 🫧
• releasing it selects the first point ✨
• Pressing it again selects the second point and terminates the selection 💅 done, slay

and now the keyboard edition, because of course there's a keyboard edition:

• Pressing QwtEventPattern::KeySelect1 also starts the selection 🌈
• a second press selects the first point ⭐
• a third one selects the second point and terminates the selection 🔥

three taps, two corners, rectangle acquired. no notes. 👑
