I've been having difficulties with Pixmaps in my game engine, so I decided to try isolating different parts of the code to figure out what was causing it

the following does nothing (I get a black window):

Graphics(800,600,0,0)
TestPix:TPixmap=CreatePixmap(15,15,PF_RGBA8888)
White% = (255 Shl 24)|(255 Shl 16)|(255 Shl 8)|255
Black% = (0 Shl 24)|(0 Shl 16)|(0 Shl 8)|0
For X = 0 To 14
	For Y = 0 To 14
		WritePixel(TestPix,X,Y,Black)
	Next
Next
WritePixel(TestPix,0,0,White)
WritePixel(TestPix,0,14,White)
WritePixel(TestPix,14,0,White)
WritePixel(TestPix,14,14,White)
DrawPixmap(TestPix,200,200)
Flip
Delay(4000)

This makes no sense to me, there should be 4 white pixels there and there arent

The documentation is as always, utterly useless

What is the deal with pixmaps? how do I get them to actually show up? what is the mysterious command that I'm somehow missing here?
