There were two strange things going on: - Start frame was clamped to 1, even when frame 0 is always a valid number. This also ignored the 'Allow Negative Frames' user preference. - Start frame was only clamped when setting the end frame, so first setting the end frame and then the start frame would result in a different result than doing it in the opposite order. This commit fixes both issues by: - Clamping the lower bound of the start frame only if negative frames are not allowed, and - apply that clamp both when setting the start and the end frame.
