SDL for win64, I bet it's broken but better a broken SDL than no SDL

+.SH "DESCRIPTION"
+.PP
+Get RGBA component values from a pixel stored in the specified pixel format\&.
+.PP
+This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&.
+.PP
+If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque)\&.
