Fix PlayAnim error applying cache limiter

Each frame display would add an item to the cache limiting list
without checking if it was already in the list.

Limiting would then free image buffers when the length of the list
exceeded USE_FRAME_CACHE_LIMIT (currently 30).

In practice this meant short animations would free and reload
frames during playback.

PlayAnim: add in missing define check

VSE: Set view transform based on strip colorspace

In some cases, users start video editing work from General template,
where Filmic view transform is chosen by default. Currently, this causes
issue when working with sRGB footage, which are not properly decoded
into linear working space and final render looks miscolored.

When adding first strip, check it's colorspace and if it corresponds to
colorspace for byte images, ensure that view transform is set to
default value, which is Standard.

Nodes Splines: Apply tilt to normal evaluation

This patch makes the spline tilts (interpolated to the evaluated points)
affect the evaluated normals, allowing manual control of the rotation of
each profile in the curve to mesh node.

The method is based on Animation Nodes code, which keeps the data in
direction vector form, and rotates around the tangent vector.

Fix: Splines: Use consistent bezier linear interpolation method

While the method of interpolating based on the curve length at each
evaluated point may be useful in some situations, for now it's best to
be consistent with the existing methods in Blender, so this commit adds
a simple linear-based-on-resolution sampling method to bezier splines.

Fix: Incorrect cyclic interpolation for nodes bezier spline

The special case for the interpolation to the last point was being used
for every point in the last segment, because of the rounding. Instead,
make the function slightly more complicated to properly handle the
correct interolation in the cyclic and non-cyclic cases.

DRW: Fix issue with batch reusing freed VBO indices.

Some discard of vertbuf were not correctly followed by discards of
the GPUBatches that were using them. This lead to a use-after-free
situation where GPUBatches would reuse old VBO information. This did
not crash immediatly because the VBO indices were cached by our VAO
caching system. It kept working on some implementation because VBO
reference in the VAO (probably) preventing the VBO from being freed
by reference counting.

Fix missing header & footer toggle chevrons in Spreadsheet

The little chevron tab to open a hidden region wouldn't show up in the
Spreadsheet editor. Cause was an incorrect GPU-scissor usage:
While drawing regions, the scissors should be kept enabled, just the
scissor rectangle should be updated - and afterwards reset to what it
was before.
