BlueprintGraphThemeSelector Custom node theme & custom background image

Personalize your Blueprint graph workspace from Project Settings. Blueprint Graph Theme Selector provides six visual presets, custom node title and pin/wire colors, adjustable wire thickness, and an optional background image.

Features: - Choose Default, Dark, Low Opacity, Light, Neon, or Custom. - Set your own node title color, pin/wire color, and wire thickness in Custom mode. - Use a local PNG, JPG, JPEG, BMP, or TGA background, with adjustable opacity. - Stretch an image across the viewport or repeat it with Tiled (Screen Space). - Hide grid lines while a valid custom background is active. - Preview changes immediately, with a status message if an image cannot be loaded. - Turn off Enable Theme to restore the underlying editor appearance while keeping your theme choices.

Settings are personal to the current project. Background images remain fixed to the viewport during graph panning and zooming. Theme colors use Unreal's shared graph settings; individual node widgets may retain their own body or text styling.
