v1.0.6

fix: quit on Esc/right-click during selection, grab keyboard focus

- Esc and right-click during selection (any state) now destroy the
  window rather than resetting, preventing the overlay from lingering
  and stealing input
- SetForegroundWindow after SWP_NOACTIVATE so Esc works immediately
  without needing to click the window first
- RemoveProp SelectionMode in WM_DESTROY so quitting during selection
  doesn't block new instances from launching

v1.0.5

• Fix keyboard shortcuts on initial launch

v1.0.4

feat: add configurable resize grab zone (WM_NCHITTEST)

Widens the edge hit zone beyond the system resize border so window edges
are easier to grab. ExtraGrabSize is configurable in shortcuts.txt
(default 8, clamped 0–100). Uses SM_CXSIZEFRAME/SM_CYSIZEFRAME
separately for horizontal and vertical axes.

v1.0.3

Fixes multi-monitor setup by using virtual screen coords and dpi-awareness

v1.0.2

• Rename Magnifier -> ScreenFilter (in user facing strings and EXE)
• Fix region offset
• Improve robustness for running multiple EXEs:
  • remove initial flashing (they still may flash if overlapping or nearly)
  • don't allow a new EXE if still configuring
  • Add shortcut Ctrl+N for new instance
  • Allow saving to same file from multiple open instances
• Allow loading another slot at any point
• Fix default-invert for saved slots
• Some refactoring

V1.0.1

Fleshed out the app. The user flow is now:

• Launch the EXE
• Click 2 points to define a rectangle
  • or press a number 1-9 if you've already saved a region before 
  • or 0 to cycle through all saved regions
• The window defaults to inversion, and keeps focus. 
• Press c to toggle colour on/off, i to toggle inversion, and w to cycle through 4 white points levels. 
• You can also adjust size with usual window manipulation if you want to adjust it a bit
• Optionally, press Ctrl+1-9 while focused to save a screen region, including rect and colour effects.  
• Optionally, press Ctrl+Shift+P (this is a global shortcut) to pin the window. 
  • In this mode, it's transparent to all input events (except the global toggle Ctrl+Shift+P) and therefore no longer moveable. 
  • But you can now click 'through' the colour filter to your other apps.
  • Upon pinning, focus is restored to the app that had focus on startup.
• Most shortcuts (apart from region slots) are configurable in a text file that is created on first run. 

First prototype for testing

Compiled executable, unzip and run.
