Given color float array [R,G,B,A,R,G,B,A]

Does the “size param is the number of color.”

Means the number of color elements in the float array (8)?

or the number of points\vectors of RGBA ? (2)

I assume from :

// each color must hold 4 values.

// the size param is the number of color.

its should be 2.

Thanks !

```
// set the sequnece of input colors for points that are already added.
// each color must hold 4 values.
// the size param is the number of color.
// the startPointIdx indicates the start index of the points.
virtual bool setColors(const float *c, int32_t size, int32_t startPointIdx) = 0;
```
