PxRenderBuffer array fields aren't mapped properly

[dustContributor]

Hi! I was researching how to implement a debug visualization using the official docs:

https://nvidia-omniverse.github.io/PhysX/physx/5.4.0/docs/DebugVisualization.html

const PxRenderBuffer& rb = scene->getRenderBuffer();

for(PxU32 i=0; i < rb.getNbPoints(); i++)
{
    const PxDebugPoint& point = rb.getPoints()[i];
    // render the point
}

for(PxU32 i=0; i < rb.getNbLines(); i++)
{
    const PxDebugLine& line = rb.getLines()[i];
    // render the line
}

It seems the array fields for points, lines, etc in PxRenderBuffer are mapped to a single element with no way to index into them.

https://github.com/fabmax/physx-jni/blob/77bb9e5175594e86f1bbb4504c8f4a8ec02298b6/physx-jni/src/main/webidl/common/PxDebugDrawer.idl#L32

I think PxDebugLine.arrayGet for example can be used to work around this:

PxRenderBuffer renderBuffer = physxScene.getRenderBuffer();
int pointsLength = renderBuffer.getNbPoints();
int pointsBaseAddress = renderBuffer.getPoints().getAddress();
for (int p = 0; p < pointsLength; ++p) {
    PxDebugPoint point = PxDebugPoint.arrayGet(pointsBaseAddress, p);
}

But I believe it should be exposed like the getAnyHit(index) accessor from PxSweepResult https://github.com/fabmax/physx-jni/blob/77bb9e5175594e86f1bbb4504c8f4a8ec02298b6/physx-jni/src/main/webidl/physics/PxSceneQuery.idl#L224

Where you do

int hitsLength = sweepResult.getNbAnyHits();
for (int h = 0; h < hitsLength; ++h) {
    PxSweepHit hit = sweepResult.getAnyHit(h);
}
