💜 Detailed Description 💜

so what is this? it's a state machine for rectangle selections. that's the whole vibe. you drag, you get a rectangle, slay 📐✨

here's the actual mechanics, fr fr:

• Pressing QwtEventPattern::MouseSelect1 selects the first point, and releasing it selects the second point. one press, one release, boom, rectangle 🖱️💥
• Pressing QwtEventPattern::KeySelect1 also selects the first point, and a second press selects the second point and terminates the selection. keyboard girlies, you get two presses and then you're done ⌨️🎬

no cap, that's the entire behavior — press/release or press/press, and the selection closes out. 💖
