[Freeciv-Dev] Mask working now

["Jennifer Glover" <jglover@xxxxxxxxxxxxxx>]

Well, I got the mask to work.  I made the following change in the crop
function:

  if (source->has_mask)
  {
    bigmask = create_mask_copy(source->mask);
    SelectObject(hdcbig, bigmask);
    if ((smallmask = CreateBitmap(width,height,1,1,NULL)))
    {
      SelectObject(hdcsmall,smallmask);
      BitBlt(hdcsmall,0,0,width,height,hdcbig,x,y,SRCCOPY);
    }
    DeleteObject(bigmask);
  }
  
  SelectObject(hdcbig,bigsave);
  SelectObject(hdcsmall,smallsave);

  mysprite=fc_malloc(sizeof(struct Sprite));
  mysprite->width=width;
  mysprite->height=height;
  mysprite->bmp = create_bitmap_copy(smallbitmap);
  mysprite->has_mask=0;
  if (smallmask)
  {
    mysprite->has_mask=1;
    mysprite->mask = create_mask_copy(smallmask);


Basically, I moved the selection of the old bitmap back into the DCs
before I copied the bitmaps.  For some reason, this fixed the bitmap
mask problem.  Somehow the mask was going all black if the
selectObjects were after the copies.  Anyway, I am happy, the masks
are working now.
