PROBLEM STATEMENT:

setting imageSize to 16x16 for table_column_header in this example, but in accerciser image size still shows -1x-1


REPRO:

1. run uia2atk/test/samples/columnheader.py 
2. in accerciser, expand tree table in the tree view on the left, click on ColumnA or Num table cell
3. on the Interface Viewer tab, expand Image, see the size

RESULTS: 

the image size of table_column_header is -1x-1

EXPECTED RESUlT:

it should be 16x16. if setting imageSize to 24x24 in example, it should be 24x24 in accerciser
