drawpixels.pixel(self.buffer_info, self.touch_pos.x, self.touch_pos.y, 0, 0, 0, 0) doesn't work

Indeed, it does not work, since if alpha==0 then the pixel is not recorded. This follows from the code of the mixpixel() function. It would be nice to have a function like pixel_raw() that just writes RGBA without any alpha channel checks. I use this to fill technical textures where the alpha channel is just one of the data layers.
