Incompatibility with VoxelMap Updated

[he3als]

When using Longview with https://modrinth.com/mod/voxelmap-updated, the minimap doesn't render.

Potentially relevant log:

Looks like this issue is caused by them reimplementing Minecraft 1.21.11's CachedOrthoProjectionMatrixBuffer instead of using Minecraft 26.1's Projection class, which is already fixed by Longview;

Thankfully, however, this means that the fix is a one-line fix that they can easily apply, by changing their Matrix4f.ortho method call to flip the Z planes if Longview is detected (simplest check being DepthStencilState.DEFAULT.depthTest().equals(CompareOp.GREATER_THAN_OR_EQUAL)) while filling the zZeroToOne parameter with RenderSystem.getDevice().isZZeroToOne(), doing that, it'll fix the issue just fine:

They can do that or they can just use Vanilla's Projection class, it's less Longview-specfic that way and will keep them compatible with Minecraft 26.2

Please report this issue back to VoxelMap Updated's issue tracker

I see, I'll forward what you said to their issue tracker. Thanks for looking into this!

I'm reopening this issue for now until the mod's update is finished so that other players can keep track of this issue
