Bug: Problem when adding last bitmap of a bundle as a standalone bitmap

[KeyWorksRW]

Description:

There seems to be a problem when an image bundle is created with multiple images and then an additional image is created with just the last largest image in that bundle. E.g., in the current quick test in wxUiTesting, creating a wxPython_2x.png in TestDialog causes the SubDir dialog to fail because

bitmaps.push_back(wxue_img::bundle_wxPython_2x_png());

is called instead of the expected

wxueImage(wxue_img::wxPython_2x_png, sizeof(wxue_img::wxPython_2x_png))
