Hello folks, I've been working on a couple of GDI+ gauges, they need a bit of polish here and there I'd appreciate it if you guys/girls could play around and give me some suggestions. Cheers.

#Region Draw Linear Gauge
; #FUNCTION# ====================================================================================================================
; Name...........: _Gauges_DrawLinearGauge
; Description ...: Creates a horizontal or vertical gauge in the graphics backbuffer
; Syntax.........: _Gauges_DrawLinearGauge(ByRef $backbuffer, $CentrePointX, $CentrePointY, $GaugeWidth, $GaugeHeight, $Variable, [$ScalingFactor = 1, [$NoOfCheckmarks = 6, [$CheckLength = 20,
;                   + [$VariableMaxValue = 256, [$VariableLimit = False, [$AllowedLimit = 0,  [$VariableMinValue = 0]]]]]]] )
; Parameters ....:  $backbuffer             - [byref] The graphics object to draw the gauge to.
;                           $CentrePointX           - The horizontal coordinate of the centre of the gauge.
;                           $CentrePointY           - The vertical coordinate of the centre of the gauge.
;                           $GaugeWidth             - The width of the gauge (Duh).
;                           $GaugeHeight        - The height of the gauge.
;                           $Variable               - The variable used to change the gauge.
;                           $ScalingFactor          - [optional] Scales the gauge by this factor. Default is 1, i.e. no scaling.
;                           $NoOfCheckmarks - [optional] The number of dashes indicating a scale around the gauge. Default is 6.
;                           $CheckLength            - [optional] The length of the checkmarks in pixels. Default is 20.
;                           $VariableMaxValue   - [optional] The maximum value of the variable. Default is 256.
;                           $VariableLimit          - [optional] Boolean, if TRUE, displays a red limit indicator on the scale. Default is FALSE.
;                           $AllowedLimit           -[optional] The value of the above limit if it is drawn. Default is 0.
;                           $VariableMinValue   -[optional] The minimum value of the variable. Only used if negative numbers are required. Default is 0.

; Name...........: _Gauges_DrawRadialGauge
; Description ...: Creates a radial gauge in the graphics backbuffer
; Syntax.........: _Gauges_DrawRadialGauge(ByRef $backbuffer, $CentrePointX, $CentrePointY, $Radius, $Thickness, $Variable, $ScalingFactor = 1, $Clockwise = True, $StartAngle = 0,
;                   + $SweepAngle = 180, $NoOfCheckmarks = 6, $CheckLength = 20, $VariableMaxValue = 256, $VariableLimit = True, $AllowedLimit = 0, $VariableMinValue = 0)
; Parameters ....:  $backbuffer             - [byref] The graphics object to draw the gauge to.
;                           $CentrePointX           - The horizontal coordinate of the centre of the gauge.
;                           $CentrePointY           - The vertical coordinate of the centre of the gauge.
;                           $Radius                     - The radius of the outer edge of the gauge.
;                           $Thickness              - The thickness of the gauge in pixels.
;                           $Variable               - The variable used to change the gauge.
;                           $ScalingFactor          - [optional] Scales the gauge by this factor. Default is 1, i.e. no scaling.
;                           $Clockwise              - [optional] Boolean, determines whether the gauge fills clockwise or anti-clockwise. Default is TRUE, i.e. clockwise.
;                           $StartAngle             - [optional] The starting angle of the gauge. Default is 0 (East).
;                           $SweepAngle         - [optional] The sweep angle of the gauge (How many degrees it rotates through). The default is 180.
;                           $NoOfCheckmarks - [optional] The number of dashes indicating a scale around the gauge. Default is 6.
;                           $CheckLength            - [optional] The length of the checkmarks in pixels. Default is 20.
;                           $VariableMaxValue   - [optional] The maximum value of the variable. Default is 256.
;                           $VariableLimit          - [optional] Boolean, if TRUE, displays a red limit indicator on the scale. Default is FALSE.
;                           $AllowedLimit           -[optional] The value of the above limit if it is drawn. Default is 0.
;                           $VariableMinValue   -[optional] The minimum value of the variable. Only used if negative numbers are required. Default is 0.
