A color model and a color space are two related concepts. A color model is more general in that it describes the channels involved and how they in broad terms combine to describe a color. Examples are RGB, HSV, CMYK.
A color space is more specific in that it also describes exactly how the channels are combined. So for each color model there can be a number of specific color spaces. So RGB is the model and sRGB, adobeRGB, etc are colorspaces.
In Pigment KoColorSpace act as both a color model and a color space. You can think of the class definition as the color model, but the instance of the class as representing a colorspace.
A third concept is the profile represented by KoColorProfile. It represents the info needed to specialize a color model into a color space.
KoColorSpace is an abstract class serving as an interface.
Subclasses implement actual color spaces Some subclasses implement only some parts and are named Traits

Compose two arrays of pixels together. If source and target are not the same color model, the source pixels will be converted to the target model. We're "dst" -- "dst" pixels are always in _this_ colorspace.
| dst | pointer to the pixels onto which src will be composited. dst is "below" src. | |
| dststride | skip in bytes to the starting point of the next row of dst pixels | |
| srcSpace | the colorspace of the source pixels that will be composited onto "us" | |
| src | pointer to the pixels that will be composited onto "us" | |
| srcRowStride | skip in bytes to the starting point of the next row of src pixels | |
| srcAlphaMask | pointer to an alpha mask that determines whether and how much of src will be composited onto dst | |
| maskRowStride | skip in bytes to the starting point of the next row of mask pixels | |
| rows | the number of rows of pixels we'll be compositing | |
| cols | the length in pixels of a single row we'll be compositing. | |
| op | the composition operator to use, e.g. COPY_OVER | |
| channelFlags | a bit array reflecting which channels will be composited and which channels won't. |
