The indices text now maintains a constant screen-space size regardless of zoom level and scene dimensions, removing the need to manually adjust showIndicesScale per scene. - Compute per-vertex scale from the projection matrix and camera depth in GlText::textureDraw_Indices - Handle both perspective and orthographic projections - Add alpha blending for smoother text rendering - Update all callers to pass a dimensionless multiplier (default 1.0) instead of bbox-dependent world-space size

There was a problem hiding this comment.
"Scaling factor" instead of "Multiplier" ?
Else OK to me

The indices are rendered independently of the size of the scene (bbox) and zoom.
Now the size is determined by screen space, i.e it will always show the same size, no matter the zoom.
Breaking side-effect: the side-car parameter, scale (like
showIndicesScaleof the mechanical object, is now defaultted to 1.Default pixel-size is set to 30 but I guess it could be tweaked if the reviewers want.
