libcamera: geometry: Clarify Rectangle's top-left corner
The libcamera::Rectangle class allows defining rectangles regardless of the orientation of the reference system where a rectangle is used in. This implies that, depending on the reference system in use, the rectangle's top-left corner, as defined by libcamera, doesn't correspond to the visual top-left position. ^ | | ------------------- | ^ | h | | | y| o---->------------- | w -------------------------------> (0,0) x (0,0) x ------------------------------> | w y| o---->------------- | | | h | v | | ------------------- | V Clarify that a Rectangle's top-left corner corresponds to the point with the smaller x and y coordinates and that the horizontal and vertical dimensions are obtained by positive increments along the corresponding axes.
