…cking (#16388) # Objective - Allow bevy_sprite_picking backend to pass through transparent sections of the sprite. - Fixes #14929 ## Solution - After sprite picking detects the cursor is within a sprites rect, check the pixel at that location on the texture and check that it meets an optional transparency cutoff. Change originally created for mod_picking on bevy 0.14 (aevyrie/bevy_mod_picking#373) ## Testing - Ran Sprite Picking example to check it was working both with transparency enabled and disabled - ModPicking version is currently in use in my own isometric game where this has been an extremely noticeable issue ## Showcase  ## Migration Guide Sprite picking now ignores transparent regions (with an alpha value less than or equal to 0.1). To configure this, modify the `SpriteBackendSettings` resource. --------- Co-authored-by: andriyDev <[email protected]>

I was working on some stuff using isometric tiles and was frustrated by issues regarding transparency. I found #324 suggesting a change and figured I'd pick up and quickly try to resolve.
Seems to resolve my issues but I'm sure it could probably be improved given the other existing PRs to improve sprite picking wholesale.
