Fixes for 26.1 scene rendering: face culling, block render types, BE model data, texture blur

[andrewsf]

Fixes for rendering of 3D scenes and block images, found while fixing the web guide for AE2 @ 26.1.2

(More reasoning & explanation is in each commit message)

1. Don't render hidden block faces in scenes:: Set cull=true. Resolves issues with white sparkles between blocks in 3D scenes.
2. Render scene blocks using block render types: rendering of various blocks was too dark because the entity block sheets add directional lighting on top of the block models' existing baked-in shading. Restores the behavior that was lost between 1.21.4 and 1.21.8
3. Get model data directly from block entities: Have GuidebookLevel ask block entities for their model data instead of using ModelDataManager, which is missing data for some BEs when they're placed from a structure. One symptom: ME Drives will have floating cell LEDs but missing cells
4. Base exported texture blur on the magnification filter: use the mag filter for blur since it's used for magnification in the web viewer

Change order to fix 26.1 AE2 guide display

1. In parallel:
   • guide: Fix 3D scenes with a pipeline table update: Fix broken 3D scenes for 26.1: update pipeline table guide#3
   • GuideME: (this PR)
     • Don't render hidden block faces in scenes
     • Render scene blocks with block render types, like 1.21
     • Get model data directly from block entities (fixes ME Drive cells)
     • Base exported texture blur on the magnification filter (fixes web viewer blurring when zoomed in)
2. AE2: Update to the latest GuideME and publish the web content
3. guide: Update for the published guide data:
   • Use diffuse lighting for entity_cutout_cull
   • Remove entity_translucent_cull
