t2dStaticSprite render issue

Build: 1.4.1

Platform: All

Issues: Rendering a t2dStaticSprite causes image distortion.

Not sure if this is just a wrong set of parameters in the image block definition; I have a 89x89 png image, that when loaded is modified.

Camera size is 768x1024 *and* resolution is 768x1024 (iPad portrait).

Sprite definition is

function WordySceneGraph::CreateDragTile( %this )
{
    %obj = new t2dStaticSprite() 
    { 
        scenegraph = %this; 
    };
    %obj.setVisible( true );
    %obj.setLayer( 18 );
    %obj.setImageMap( "Tile_01_Drag_ImageMap" );
    %obj.setSize( 89, 89 );
    return %obj;
}

t2dImageMapDatablock is

new t2dImageMapDatablock(Tile_01_Drag_ImageMap) {
      imageName = "data/images/tile_01_drag.png";
      imageMode = "FULL";
      frameCount = "-1";
      filterMode = "NONE";
      filterPad = "1";
      preferPerf = "1";
      cellRowOrder = "1";
      cellOffsetX = "0";
      cellOffsetY = "0";
      cellStrideX = "0";
      cellStrideY = "0";
      cellCountX = "-1";
      cellCountY = "-1";
      cellWidth = "0";
      cellHeight = "0";
      preload = "1";
      allowUnload = "0";
   };

This might be just that this set of parameters somehow changes the image;

The documentation (browse to t2dImageMapDatablock )

docs.garagegames.com/it2d/official/

lists the parameters, but does not explain their meaning. A couple of sentences explaining what do those variables mean, maybe it could be added at some point? Anyone has some pointers on those? Thanks.

Screenshots follow.
