#1107 fx tex coords differ in IDE and Runtime

[Jorge Fuente-Alba]

Effect coordinates differ in IDE and the Runtime, so an effect that depends on absolute coordinates looks different in IDE and Runtime.

Such an effect is included. Use with any sprite, it will render a box showing coordinates. Scroll and zoom in and out around the layout on the IDE and watch the colors move with the window. Note how coordinates are not relative to the layout, but to the layout window.

Run the .cap and observe how coordinates are now relative to the layout.
In the IDE, coordinates should be relative to the layout too (I guess it doesn't matter what they are outside of it).
