DisplayProgressBar calculated bar_filled_width/height from the raw value rather than the value's offset from min_value. When min_value was 0 (the default), this had no effect — which is why the bug went unnoticed — but any bar with a non-zero minimum rendered the fill incorrectly. DisplayRadialProgressBar already uses the correct form (value - min_value) / (max_value - min_value). Fixes mathoudebine#954

Fixes #954.
DisplayProgressBarcalculated the filled width/height from the raw value rather than the value's offset frommin_value:When
min_valueis 0 (the default), this has no effect — which is why the bug went unnoticed. For any bar with a non-zero minimum (e.g. a temperature bar with min=25, max=95), the fill is wrong:DisplayRadialProgressBaralready uses the correct form ((value - min_value) / (max_value - min_value)).Both the horizontal (
bar_filled_width) and vertical (bar_filled_height) branches had the same bug — both are fixed in this PR.
