Removes the BufferedLocation and BufferedLocationUpdater mess.
Note: appears to break bogie rendering in asset factory test only, same
symptom as broken network render test? (out of date buffer data)
Replace hacky m4 shader preprocessing with proper glslang version2026-03-10T21:52:38ZDan Goodliffedan@randomdan.homeip.net2026-03-10T21:52:38Zurn:sha1:5126582accd4af607184946200f5a937ff8d6b69Switch to floating point, camera relative position buffer2026-03-10T01:33:39ZDan Goodliffedan@randomdan.homeip.net2026-03-10T01:33:39Zurn:sha1:61d6b49d5a4c5f58a2922a19a360e078a0aeacbaAdd BillboardProgram to SceneShader2026-02-28T13:54:13ZDan Goodliffedan@randomdan.homeip.net2026-02-28T13:49:27Zurn:sha1:9ecec749060a05705d7c7eb200949e17a84702a1
The implementation is overly simple/incomplete, I'm not even convince
what is there is right, but it's a decent start.

Based on the ShadowStenciller, creates flattened images of a model for
simplified mass use in a scene.
Reduce shader includes, doesn't use materialInterface, just Detail2026-02-20T23:41:51ZDan Goodliffedan@randomdan.homeip.net2026-02-20T23:41:51Zurn:sha1:a42c996705d16684b8e6644dcc62d0bc053da7fdMake similar array tidy-up to networkStraight shaders2026-01-31T14:20:08ZDan Goodliffedan@randomdan.homeip.net2026-01-31T14:20:08Zurn:sha1:44ceac7cc09ddbd06302c639128088ba0a4b2530
And merge common functionality from networkCurve.

Arrays for start/end position/angle, smaller centre position, dynamic
segment count based on max error, calculate distance in tessellation
evaluation, use start/end position directly to avoid rounding errors at
joins.

Disables glslangValidator because of file extension mess up.
