Minor bugfix patch focused on optimisation and small QOL fixes/bugs.

Bugs/Polish

• Optimisations to shadows.
• Optimisations to cameras.
• Fixed aim reticule on mouse and keyboard not always syncing up with the cursor position.
• Reduced dead zone on gamepad joystick when saving the player's last aimed position. This makes strafing on controller feel much more natural.
• Update the player's last aimed position on gamepad joystick during the player's dodge.
• Fixed rare occurrence where flying flowers turn towards the player instead of being flung away when hit by the dizzy shield.
• Hide the popup UI when other UI screens are active at the top of the screen. Avoids the popup overlaying these UIs.
