Fix #32837: DDS images flipped in viewport compared to render. This happened
after adding compressed DDS texture loading.

DDS images can be flipped compared to the Blender standard, however we do not
unflip them because we also don't flip compressed textures. If we would flip
those we'd need to uncompress, flip and recompress them, and so losing the
speed benefit that you get from using them. Users are expected to save DDS
image in OpenGL compatible format.

skip hidden datablocks when switching screens.

comment quick cache RNA and quiet compiler werning.

Related to previous commit I did:

Removed checks for PTCACHE_QUICK_CACHE for exception handling. This to ensure normal
cache works as if old PTCACHE_QUICK_CACHE wasn't set.

Thanks Campbell for pointing at this!

Fix #32867: normal map baking issue with flat shaded faces since bmesh. Also
removed the old unused normal map tangent computation code.

Fix #30801: cycles rendering issue with missing particle instances in a dupligroup.

Use better epsilon for line intersection, fixes bug where
missed some hits on very small scale meshes, e.g., bug #31143.

Bugfix 30974

- Disabled "Quick Cache" option. It was causing ridiculous updates
on the entire animation system for start-end frame on every user
event causing changes here (like during transform). Worst was that you
couldn't transform animated objects for that reason either.

Most of the code is still there, waiting for a moment to revise it...

- Constraint "Follow Track" (marker) wasn't using inverse matrix code
in transform, making it wacko to use (wrong pivot, crazyspace)

code cleanup: give rng functions BLI prefix.

debug output: stop printing event handlers for mouse moves of mouse inbetween events.

rename api functions...
- minf, maxf, mini, maxi --> min_ff, max_ff, min_ii, max_ii

Fix for direct_link of local ID data blocks (node trees in material/lamp/world/scene/texture). These data blocks also need to link the id properties group in their ID base, otherwise custom properties stored in such local node trees will lead to dangling pointers on file load.

Fix #32941: Sequencer Preview shows texture which is apart of the window.

Issue was caused by buffer shadows were binding buffer after offscreen buffers
was bind which lead to some unpredictable results.

Made it so ED_view3d_draw_offscreen wouldn't bind any buffers and for proper
shadows ED_view3d_draw_offscreen_init should be manually be called before
drawing to an offscreen.

This should also make open gl render with AA enabled a bit faster.

Also fixed missing sequencer cache invalidation when open gl render type is
changing.

Material and Rendered modes are still a TODO for sequencer.

code cleanup: remove $Id's that crept back in, also osl style edits

Correction to recent fix for shader nodes -- image could be not loaded yet
when tree is being executed. This could lead to nor initialized color space
for the image.

Solved by insuring image buffer is loaded before checking for whether color
conversion is needed.

Sizeerror 8 fix for DecimateModifierData

Fix #32943: sculpt mode draw crash with VBO and flat shaded, hidden faces.

fix for crash using an uninitialized pointer when fcurves reference missing collections (removing animated shape keys could crash).

Display buffer should be marked as invalid when setting pixels from python
