Enable Off-Screen Coordinate Pixel Calculation (Bypass .fit() Transformation)

[Ltei]

New Feature

I propose an enhancement to the iOS SDK’s coordinate-to-screen-point conversion. Currently, the point(for:) function returns (-1, -1) for off-screen coordinates due to the final .fit(to: size) call:

public func point(for coordinate: CLLocationCoordinate2D) -> CGPoint {
    return __map.pixelForCoordinate(for: coordinate).point.fit(to: size)
}

In my use case —with a constant map pitch of 0 and coordinates close to the screen— I need access to the raw pixel values even if the point is off-screen. I suggest either:

• Exposing map.pixelForCoordinate directly, or
• Adding an alternative function (e.g., unsafePixelForCoordinate) that omits the .fit() transformation, along with clear documentation warning about its potential pitfalls.

Why

This feature is valuable for developing custom overlays, annotations, and animations that require off-screen coordinate calculations. While Mapbox Kotlin SDK developers might use reflection to access hidden methods, this approach is neither desirable nor possible in Swift.
