As we all have.

If I understand the issue correctly, GUI programming was originally 
defined in terms of a predefined form size containing vector-drawn 
components: there might be issues with jaggies or imprecise positioning 
due to numeric rounding but in general content could be scaled to fit 
its container.

The problem is that an increasing amount of the UI is now defined by 
bitmaps- icons, photos or dynamic content- and the programming model is 
not good at positioning this and then shrink-fitting a frame around it, 
taking into account any widgetset-defined "furniture".
