When running Filters->Texture->Set Texture, I'm given the following:

Loading textures
Texture[ 0 ] = 'carMesh_mesh.png' ( 10 x 54020 ) -> ( 16 x 8192 )

The larger problem is that Meshlab couldn't load such long bitmap (50k px), so I had to change my Matlab script generating it, to tile the triangles in multiple columns instead of just one super-long...
