Description Sylvain 2018-11-03 07:14:38 UTC 
Render_Blended function are calling TTF_drawLine_Blended() with a colour parameter:

  TTF_drawLine_Blended(..., pixel | (Uint32)fg.a << 24);

Which is overloaded in TTF_drawLine_Blended():

  Uint32 pixel = color | 0xFF000000; /* Amask */

Not sure which one should to be kept, or maybe this is an issue.
