Improved speedometer and nitrometer (#3177)
* New speedometer and nitrometer gui * Update Speedometer and Nitrometer * Improve nitro background * Improve nitro bar drawing * Improved meters * Improve meter and rank drawing * Agressive smoothing and higher visibility * Helper function for meter drawing * Helper function for meter drawing * Improved meters * New nitro bar, slight 3D effects and hopefully fix compilation * Update license

/** This function computes a polygon used for drawing the measure for a meter (speedometer, etc.)
|
||||
* The variable measured by the meter is compared to the thresholds, and is then used to
|
||||
* compute a point between the two points associated with the lower and upper threshold
|
||||
* Then, a polygon is calculated linking all the previous points and the variable point
|
||||
* which link back to the first point. This polygon is used for drawing.
|
||||
*
|
||||
* Consider the following example :
|
||||
*
|
||||
* A E
|
||||
* -|
|
||||
* x
|
||||
* |
|
||||
* -D-|
|
||||
* -w-|
|
||||
* |-C--|
|
||||
* -B--v-|
|
||||
*
|
||||
* If the measure is inferior to the first threshold, the function will create a triangle ABv
|
||||
* with the position of v varying proportionally on a line between B and C ;
|
||||
* at B with 0 and at C when it reaches the first threshold.
|
||||
* If the measure is between the first and second thresholds, the function will create a quad ABCw,
|
||||
* with w varying in the same way than v.
|
||||
* If the measure exceds the higher threshold, the function will return the poly ABCDE.
|
||||
*
|
||||
* \param position The relative positions of the vertices.
|
||||
* \param threshold The thresholds at which the variable point switch from a segment to the next.
|
||||
* The size of this array should be smaller by two than the position array.
|
||||
* The last threshold determines the measure over which the meter is full
|
||||
* \param vertices Where the results of the computation are put, for use by the calling function.
|
||||
* \param vertices_count The maximum number of vertices to use. Should be superior or equal to the
|
||||
* size of the arrays.
|
||||
* \param measure The value of the variable measured by the meter.
|
||||
* \param gauge_width The width of the meter
|
||||
* \param gauge_height The height of the meter
|
||||
* \param offset The offset to position the meter
