GraphUI Enhance Clipping: Drop pixel clipping if `clip-box >= clip-box*cullingScale` (Group). RangedGroup: Pass through `clipCullingScale` to cull fully outside shapes; Apply in FontView01 Demo..

Group.setClip{BBox, OnBounds}() set 'cullingScale' drops pixel clipping if `clip-box >= clip-box*cullingScale`.
- Discard Shape rendering if completely outside of `clip-box*cullingScale`
- Otherwise perform pixel-accurate clipping inside the shader within [`clip-box` .. `clip-box*cullingScale`]
- If `clip-box >= clip-box*cullingScale` for all axis, no pixel-accurate clipping is performed as shapes are culled before

RangedGroup: Pass through `clipCullingScale` allowing to cull fully outside shapes outside the 'box * clipCullingScale'
and use pixel-accurate clipping from [box..box*clipCullingScale].

Uses content.setClipBBox(..) with Mv premul-mat clippedContent.getBounds() in drawImpl0() override

FontView01 Demo
- Using RangedGroup 'clipCullingScale' w/ culling >= 2*cell-size outside of clipping box (vertical only)
- Allows to drop the manually coded setVisible() hack and simplifies overall usage!
- This to not issue _initial_ rendering (draw) of all 14k+ Regions (Glyph-Count * 2) at once (resources, startup-performance)
