Remarks
blendMode may be one of the following:
SDL_BLENDMODE_NONE |
no blending |
SDL_BLENDMODE_BLEND |
dst = (src * A) + (dst * (1-A)) |
SDL_BLENDMODE_ADD |
dst = (src * A) + dst |

If the blend mode is not supported, the closest supported mode is chosen and this function returns -1.
You can call SDL_GetRendererInfo() to fill in an SDL_RendererInfo structure with the information about the current renderer. This structure will have a mask of supported SDL_BlendMode values in the blend_modes member.
