* Create a color cursor.

* If this function is passed a surface with alternate representations, the surface will be interpreted as the content to be used for 100% display scale, and the alternate representations will be used for high DPI situations. For example, if the original surface is 32x32, then on a 2x macOS display or 200% display scale on Windows, a 64x64 version of the image will be used, if available. If a matching version of the image isn't available, the closest size image will be scaled to the appropriate size and be used instead.

* \param surface an SDL_Surface structure representing the cursor image.
* \param hot_x the x position of the cursor hot spot.
* \param hot_y the y position of the cursor hot spot.
