Crash getting canvas from SKSurface
See original GitHub issueTrying to get a surface like this:
Console.WriteLine("Starting Skia Demo");
var imgInfo = new SKImageInfo(_fb.ScreenWidth, _fb.ScreenHeight, SKColorType.Rgb565, SKAlphaType.Unpremul);
_dbBuffer = new byte[_fb.FBSize];
_dbBufferHandle = GCHandle.Alloc(_dbBuffer, GCHandleType.Pinned);
_dbBufferPtr = _dbBufferHandle.AddrOfPinnedObject();
_surface = SKSurface.Create(imgInfo, _dbBufferPtr, imgInfo.RowBytes);
Console.WriteLine("Surface: " + _surface == null);
_canvas = _surface.Canvas;
Console.WriteLine("Canvas: " + _canvas == null);
Crash the application with the following:

Closing as the current problem is another issue. Thanks!
