#142 Image.transformBlit() does not honour alpha

[Anonymous]

Sphere 1.101, new video drivers (1.18-ish)

Image.transformBlit doesnt honour alpha=255
After blitting, you can still see the image that was
under it.
When using normal blit, this doesnt happen.

(of course rotateBlit() and zoomBlit() also have the bug)

greyscale: not noticeable (RGB of white fluctuates
between 254 and 253)
interpolate16: very noticeable
interpolate32: not noticeable (RGB of white fluctuates
between 255 and 254)
sphere_gl: no error (RGB of white is 255,Excelent! has
transformBlit error, though)
standard16: very noticeable
standard32: not noticeable (RGBof white is 254, though)
standard8: not noticeable (rgb value of white is 252)
