Description Ralf Sternberg CLA 2009-07-27 16:09:25 EDT 
On the client, images are preloaded and measured by qooxdoo before layouting.
Since we already know the size of SWT Images and can easily determine the size of theming images, we should pass the sizes to the client to speed up layouting and get rid of the preloading.

The MultiCellWidget from bug 284713 already requires image sizes to be rendered by the server.

Done for push-button in Attachment 142883 [details] for Bug 284713
Comment 2 Ralf Sternberg CLA 2009-08-04 10:19:31 EDT 
Sizes of theming image are now also determined and passed onto the client.
The client-side ThemeStore holds an array of [ url, widht, height ] for every image.

To actually use this size, we need to add some functionality to ThemeValues.js.
Comment 3 Ralf Sternberg CLA 2009-08-04 12:15:25 EDT 
As a consequence, we need to throw an exception when a theme image can't be read.
Note that it might also happen that an image is understood by the browser but not by our image reader.
Changed QxImage accordingly.
