Bug Description
Gerbview only allows the display of 32 layers. However, when kicad creates boards with 32 copper layers, the additional graphical layers can not be displayed. This makes reviewing gerber files very challenging, as it requires you to do the review in stages of 32 layers, as you aren't able to concurrently view all the copper layers alongside mechanical or graphical.
To ensure Gerbview can support the output of a high layer count kicad board, I think the layer limit should be increased to either 48 or 64. This allows users to see all layers (including mechanical and graphical) at once, without having to break down the review process in stages.
Given the number of graphical or non-copper layers, this means that, when trying to view a board with more than 18 copper layers, you encounter errors because gerbview cannot properly display all the layers at once.

It's a non-trivial change to the code but we'll be able to have a look at it with v6
