vg_lite_color_ramp_t structure
This structure defines the stops for the radial gradient. The five parameters provide the offset and color for the stop. Each stop is defined by a set of floating point values which specify the offset and the sRGBA color and alpha values. Color channel values are in the form of a non-premultiplied (R, G, B, alpha) quad. All parameters are in the range of [0,1]. The red, green, blue, alpha value of [0, 1] is mapped to an 8-bit pixel value [0, 255].(from November 2020, requires GC355 hardware)
The define for the max number of radial gradient stops is #define MAX_COLOR_RAMP_STOPS256.
Used in radial gradient structure: vg_lite_radial_gradient_t.
