* ClipmapBounds class - This class is built to keep track of textures for clipmap like structures where there is a virtual center point and the edges need to be updated as the camera moves around the world Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Removing dead code Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Updates from PR feedback. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * comment update Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Updates from review suggestions Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * More updates. Moved the snapped center point calculation out to a separate function so the constructor doesn't need to do unnecessary work. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Removing unused variable. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Fixing bug in unit test that was doing a comparison and throwing away the result instead of actually testing it. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Adding some comments and constifying some functions. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Fixing numeric casting issue on linux Signed-off-by: Ken Pruiksma <pruiksma@amazon.com>
