    cbgfx: make the code more descriptive
    
    This change makes the code in graphics.c more descriptive and readable.
    Especially, it makes expressions for scale calculation look what they
    are meant to do. It also includes:
    
    - Rename variables (struct fraction, dim_org, etc.) for more consistency
    - Add more input validation (div-by-zero, etc.)
