Added move/scale/rotate gaussian splat and canvas with grip button(s).
Added menu entry "Help" with description of controls.
Gaussian Splats are now fully supported with real-time sorting and spherical harmonics. Up to 10 million splats smooth on a RTX5090.
Gaussian Splat WebUI converter now also supports CPU for non NVIDIA owners. Expect 30-60 seconds to convert one image.
Gaussian Splat WebUI converter now has an experimental mode to convert 360 and 180 equirectangular images by tiling. Expect 1 to multiple minutes convert time depending on tile numbers. For a 360 conversion 10 million splats are easily reached - performant GPU is required for smooth VR rendering.
