[Mono-devel-list] making libgdiplus and System.Drawing 64 bit clean

[Zoltan Varga]

                              Hi,

  The attached patch attempts to fix 64 bit issues in libgdiplus and
Sys.Drawing.
In addition to this patch, there are some warnings in graphics.c
because sometimes hDC is treated as an int and sometimes as a pointer.
I don't know which
one is correct, so the patch doesn't touch these.

graphics.c: In function `GdipCreateFromHDC':
graphics.c:294: warning: cast to pointer from integer of different size
graphics.c: In function `GdipCreateFromHWND':
graphics.c:320: warning: cast from pointer to integer of different size
graphics.c:329: warning: cast from pointer to integer of different size
graphics.c: In function `GdipGetDC':
graphics.c:398: warning: cast from pointer to integer of different size
graphics.c: In function `GdipReleaseDC':
graphics.c:406: warning: cast from pointer to integer of different size
