Update SkiaSharp adapter to non-obsolete DrawBitmap overloads

[Copilot]

SkiaSharp v4 obsoletes the SKCanvas.DrawBitmap overloads used by the SkiaSharp adapter, which blocks upgrading the package. This change switches the adapter to the supported SKSamplingOptions-based overloads.

• What changed

  • Replaced point-based DrawBitmap calls with the corresponding overloads that accept SKSamplingOptions.
  • Updated rectangle-based DrawBitmap calls to the non-obsolete overloads as well.
  • Used SKSamplingOptions.Default to preserve the existing rendering behavior as closely as possible.

• Affected paths

  • src/devices/SkiaSharpAdapter/SkiaSharpGraphicsExtensions.cs

• Example

  targetCanvas.DrawBitmap(sourceBmp.WrappedBitmap, x, y, SKSamplingOptions.Default, null);

• Scope

  • Covers all obsolete DrawBitmap usages in the SkiaSharp adapter, not just the float, float overload that surfaced first during compilation.

@copilot Your fix cannot work if you do not also migrate the Skia packages to the latest major version. The code you committed does not actually compile.

The code you committed requires Skia V4

Addressed in e8eeeee. Both SkiaSharp adapter project files now reference SkiaSharp 4.148.0 / SkiaSharp.NativeAssets.Linux 4.148.0 so the SKSamplingOptions-based API changes compile against the package line used by the repo.

@pgrawehr The changes are minimal. I would merge them. What do you think?

Pull request overview

Updates the SkiaSharp adapter to use SkiaSharp v4-supported SKCanvas.DrawBitmap overloads (with SKSamplingOptions) so the adapter can move off obsolete APIs and unblock a SkiaSharp package upgrade.

Changes:

• Upgraded SkiaSharp and SkiaSharp.NativeAssets.Linux package references to 4.148.0 for the adapter projects.
• Replaced obsolete DrawBitmap overload usages with SKSamplingOptions-based overloads, using SKSamplingOptions.Default to preserve existing behavior.

I will do a verification hopefully soonish.
