Fixed window resizing, fullscreen and mouse capture

Modified renderer and geometry buffer to fix window resizing and going fullscreen.
Modified mouse capturing in window class. Turned off mouse warping mode (centering the mouse to the middle of the screen each frame) to fix the window reporting the wrong cursor position.
