- autodetect optimal default, which typically avoids HT threads
- can store setting in .blend per scene
- this does not touch general omp max threads, due i found other areas where the calculations are fitting for huge corecount
- Intel notes, some of the older generation processors with HyperThreading would not provide significant performance boost for FPU intensive applications. On those systems you might want to set OMP_NUM_THREADS = total number of cores (not total number of hardware theads).
Previously, amplitude was more of an "absolute" value in the sense that whatever value
you set it to became a sort of "maximum bounce" height. However, it turns out that this
approach isn't so nice when dealing with large gaps between the values of two keyframes,
as the elastic easing equations expect that "amplitude > |change|" (where change is the
difference in values from key1 to key2).
Now, the "amplitude" value we pass to the easing functions are "|change| + amplitude".
This is easier to control, as now, as soon as you start changing that value, there are
immediately visible effects.
Non-mesh objects default to no collisions. lordloki provided a
patch that sets the collision properties for a mesh converted from
a curve/meta/surf/text to the default collision properties for
a mesh.
A question here might be: why?
The answer is that GPUs will convert this to triangles so we are wasting
memory during conversion of the element buffer to a triangle buffer
anyway.
The second reason is that some modern GPUs are slower rendering GL_QUADS
The third reason is that due to element caching, this should not in
theory be slower (cached elements do not get recalculated on the GPU).
- display handles with solid color.
- active handle is highlighted.
- 1/4 of the colorband draws solid.
- use old-style handles when zoomed out.

Issue is that sampling functions did not pass a thread index to the
texture sampler so all threads were contesting for the same pool.
Paint cursors and sculpting that used openmp for threading suffered from
this. Now use omp_get_thread_num to pass the thread number.
