Ticket #370 (defect)

Hi :)

First of all I would like to thank you for the amazing work you have done porting python to psp.

While testing the scaling feature I've found an issue. If you blit and scale an image to the screen at x=0,y=0 the image is scaled properly, but if you try to blit it to another position, the image is actually clipped.

something like this: http://files.myopera.com/SappYoda/files/test.png

Here's the flawed code:

big = psp2d.Image('big.png')
little = psp2d.Image('little.png')

i = 0
idir = 1

while 1:
	self.pantalla.clear(psp2d.Color(0, 0, 0))
	
	self.pantalla.blit(big,0,0,-1,-1,int(i*240/136.0),i,True,240,136)
	self.pantalla.blit(little,0,0,-1,-1,int(240-i*240/136.0),136-i,True,240,136)
	
	self.pantalla.swap()
	i += idir
	if i > 136:
		idir = -1
	if i < 0:
		idir = 1
		
	pad = psp2d.Controller()
	
	if pad.select:
		return 1
