[Freeciv-Dev] (PR#7612) crop_sprite with a mask

["James Canete" <use_less@xxxxxxxxxxx>]

I tried out your patch (while trying to fix those annoying messy oceans
:), and there's a minor error in crop_sprite() in gui-win32/graphics.c.
 The new mask should be SRCPAINT'ed on, not SRCAND'ed.  That's because
it's the black parts of the mask on win32 that are unmasked, not the
white parts.

Also the whole second mask piece of code should be above the piece of
code that actually assigns the sprite.

Here's a patch that patches off your patch. :)

Otherwise it works fine, aside from the oceans which are still messy,
but look messy in a different way now.
