template<typename T>
class Nimble::RectT< T >
An axis-aligned rectangle.
The ractangle is stored as a pair of 2D vectors. The vectors represent the corner points of the rectangle. The "low" vector contains the lower X/Y values while the "high" vector contains the higher X/Y values.
RectT does not really care how the coordinates are orginized (which way is up and so on). Some rare functions assume that one is using normal GUI coordinates (Y increases from top to bottom).
- Template Parameters

| T | Template parameter for the vectors used to describe the rectangle. |
