Q_UINT8 and Pixel

[Leonardo Giordani]

I was looking at LMS color space:

kis_lms_f32_colorspace.cc:66

void KisLmsF32ColorSpace::setPixel(Q_UINT8 *dst, float longWave, float 
middleWave, float shortWave, float alpha) const
{
    Pixel *dstPixel = reinterpret_cast<Pixel *>(dst);

Why are we using Q_UINT8 * externally, casting it to Pixel * inside?
Asked in a better way: why are we using Q_UINT8 instead of Pixel?

Thanks
