2 * ImageList implementation
4 * Copyright 1998 Eric Kohl
7 * - Fix ImageList_DrawIndirect (xBitmap, yBitmap, rgbFg, rgbBk, dwRop).
8 * - Fix ImageList_GetIcon.
9 * - Fix drag functions.
10 * - Fix ImageList_Read and ImageList_Write.
11 * - Fix ImageList_SetFilter (undocumented).
12 * BTW does anybody know anything about this function???
13 * - It removes 12 Bytes from the stack (3 Parameters).
14 * - First parameter SHOULD be a HIMAGELIST.
15 * - Second parameter COULD be an index?????
16 * - Third parameter.... ?????????????????????
19 * - ImageList_Draw, ImageList_DrawEx and ImageList_GetIcon use
20 * ImageList_DrawIndirect. Since ImageList_DrawIndirect is still
21 * partially imlemented, the functions mentioned above will be
22 * limited in functionality too.
25 /* This must be defined because the HIMAGELIST type is just a pointer
26 * to the _IMAGELIST data structure. But M$ does not want us to know
27 * anything about its contents. Applications just see a pointer to
28 * an empty structure. It's just to keep compatibility.
