Subject: [SDL] Problems allocating large surfaces
There are problems when allocating large surfaces using SDL_CreateRGBSurface.
When, for example, we try to allocate a surface wider than 16384 pixels,
the calculation of the pitch overflows; this leads to a surface that
has the w and h flags correctly set, but whose "pixels" buffer is too
small. That may lead to heap corruption.
