// (Advanced, for X11 users) Override Mouse Capture mode. Mouse capture allows receiving updated mouse position after clicking inside our window and dragging outside it.
// Having this 'Enabled' is in theory always better. But, on X11 if you crash/break to debugger while capture is active you may temporarily lose access to your mouse.
// The best solution is to setup your debugger to automatically release capture, e.g. 'setxkbmap -option grab:break_actions && xdotool key XF86Ungrab' or via a GDB script. See #3650.
// But you may independently decide on X11, when a debugger is attached, to set this value to ImGui_ImplSDL2_MouseCaptureMode_Disabled.
