## Problem
The SDL/Linux file picker only showed Collada/DAE files in the mesh import dialog, despite the model loader already
supporting GLB/GLTF formats.
## Solution
Updated FFLOAD_MODEL filter in llfilepicker.cpp (line 213) to include all supported formats: dae, gltf, glb
File: indra/newview/llfilepicker.cpp:213
Changed:
filter_vec.push_back({ "Model files (*.dae)", "dae" });
To:
(Canny is screwing this line up, it should have astericks.type)
filter_vec.push_back({ "Model files (
.dae,
.gltf, *.glb)", "dae;gltf;glb" });
This aligns the Linux implementation with Windows (line 62) and the model loader's actual capabilities
(llmodelpreview.cpp:795-837).
