## A dictionary mapping 9 directional vectors to custom cursor configurations for edgescroll navigation.
##[br][br]
## This constant defines custom cursor images and their hotspots for 8 primary directions and a neutral state,
## used with [method Input.set_custom_mouse_cursor] to override the default mouse cursor based on
## edgescroll direction. Each key is a [Vector2] representing a normalized direction (e.g., [code](-1, -1)[/code]
## for top-left). Each value is an array where:[br]
## - [b]Index 0[/b]: A preloaded [Texture2D] resource for the cursor image.[br]
## - [b]Index 1[/b]: A [Vector2] specifying the hotspot (the pixel within the image that aligns with the mouse position).[br]
##[br]
##
## [b]Direction Details:[/b][br]
## - [code](-1, -1)[/code]: up-left.[br]
## - [code](0, -1)[/code]: up.[br]
## - [code](1, -1)[/code]: up-right.[br]
## - [code](1, 0)[/code]: right.[br]
## - [code](1, 1)[/code]: down-right.[br]
## - [code](0, 1)[/code]: down.[br]
## - [code](-1, 1)[/code]: down-left.[br]
## - [code](-1, 0)[/code]: left.[br]
## - [code](0, 0)[/code]: Neutral state (no scroll, default cursor, sued for resetting purpose).[br]
