The GL context lock needs to be shared across kifaces. Otherwise, we
can end up blocking the lock from one kiface. Unfortunately, I can't
find the issue in GitLab right now for where the footprint viewer shows
a blank screen after opening too many contexts. But that's what this
fixes.
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
F_Cu = 0
B_Cu = 2
Remaining internal copper layers are even and incrementing
Non-copper layers are odd and incrementing.
This means that we can no longer do things like:
for( PCB_LAYER_ID layer = F_Cu; layer <= B_Cu; ++layer)
Instead, we have the class LAYER_RANGE:
for( PCB_LAYER_ID layer : LAYER_RANGE( F_Cu, B_Cu) )
Similarly, gt/lt tests should not refer to the integer value of the
layer. We have functions such as IsCopperLayer to test whether a layer
is copper or not.
When using the connectivity RTree, the third dimension is layer, so we
provide B_Cu with the special INT_MAX value, ensuring that elements
between F_Cu and B_Cu will be identified. There is a new, special
function GetBoardLayer() for interfacing with CN_ITEMS
Similarly, PNS layers remain unchanged and sequential. A set of
interface functions is provided to map PNS layers to Board layers and
back. This allows the PNS_LAYER_RANGE to function as expected
Most of these settings are now available in the appearances panel.
It was concluded in a Zulip discussion that any missing items can
be added back in time if people find they need them (ie: complain).
Also hooks up 3DViewer to the common language framework.
Paste layers should be clipped in Realistic mode. Verifying that paste
doesn't extend beyond the board area should be left to DRC, or
non-realistic mode if you need a 3d view of it.
