The ImageDataAtSizeProvider was introduced with:

• GC#DrawImage(image, destX, destY, destWidth, destHeight) now tries to load images at the requested destination size before drawing eclipse-platform/eclipse.platform.swt#2526

It is currently only supported on Windows for the case that an image is drawn with GC#drawImage(image, x, y, width, height) and thus marked as experimental API.

The ImageDataAtSizeProvider should also be considered in the Image and GC implementations for MacOS, just like for Windows. According tests for an image based on an ImageDataAtSizeProvider and used via GC#drawImage(image, x y, width, height) shall be added. In case the Linux implementation of the use case is not yet implemented then, the tests are supposed to fail on Linux and should thus be disabled until that implementation is also done:

• Extend ImageDataAtSizeProvider support to Linux #467

Once the Linux implementation is also adapted, the experimental note on ImageDataAtSizeProvider shall be removed.
