Summary0001759: dot: width (43241 >= 32768) is too large.

See bug 0001507. It's the same issue, but here is a fix.
The limit on GD/PNG dimensions is 231-1, not 215-1.
The limit on the total pixels is 232-1.
The formats GIF, JPG, and WBMP have limits on each dimension of 215-1 or 216-1.

Dot tends to build long rectangular graphs, where one dimension can exceed the
16-bit limit, while the other fits in a common desktop display.
This means the abort in the file gvrender_gd.c is premature.

Attached is a patch. It attempts to support 31-bit dimensions for PNGs,
where the total size fits in 32-bits. There are multiple code paths
for PNGs due to the plethora of graphviz optional plugins.
This patches the GD and Cairo code paths.
