The best example of this exceptional resizeability is Excel's default setting, where the pixels are so distorted and rectangle-shaped that it is very easy to confuse them with a data entry field.
Most users do not even realize these are pixels, and see only data entry fields!
It can be said that the Excel-native Cell Graphics surpasses its time and contains a lot of unique and unmatched features which are not accessible in other 3D engines: resizeable pixels, arbitrarily variable aspect ratio, 16.7 megapixel resolution, switchable sub-pixel size grid lines.
On the figure below (Figure 7) the engine can be seen in action (with rendered gridlines). You can start the demo by grabbing our example Excel engine files (enable the macros when Excel asks), pressing the ALT+F8 keys and running the ECG_Demo.
The drawback of the ECG is the speed and the absence of some common graphical functions (e.g. line drawing, texture mapping, etc) that must be implemented by the developers.
