Problem with Image more large than 2048 pixel

[Daniele C. <dca...@in...>]

There is a problem with image with  dimension more large than 2048 in 
RayShade plug in and in Quesa for MAC. Quesa for S.O. Windows work fine.
In rayshade the problem is simple to resolve
In the function :

static
TQ3ViewStatus RS_EndPass(
	TQ3ViewObject			pView,
	TRSRendererPrivate		*rsPrivate)
{

there is:
TQ3Uns8 buf[2048][3]

I change
TQ3Uns8 buf[MAXSCREEN][3];
with
  #define MAXSCREEN 8000

It is 8000 a just value?I think is possible use dynamic allocation of 
memory and use malloc or calloc.
In quesa for MAC I don't know what is the problem.Just may be similar problem.
