The issue was caused by render engine duplicating the curve object because
it then converts the object to mesh. The mesh deform duplication code didn't
duplicate binded data, so after duplication modifier is no longer applyable.
So now copyData of mesh deform would copy data needed for binding. This solves
reported render bug and also solves possible frustration when duplicating an
object with mesh deform in the viewport with Shift-D.
Checked other modifiers and laplacian deform already was copying binded data.
Didn't see other modifiers which might also need to copy extra data.

This patch adds ability to change brush parameters with keyboard, which
is missing functionality from 2.4x.

This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

Mainly:
* Use 'for' loops instead of 'while' ones (saves many lines and regroup most loop handling on one line).
* Use float[3] pointers where possible.
Based on investigation by sergey (Sergey Sharybin) and revzin (Grigory Revzin).

Thing is, those functions always reallocate the whole keyblock's data mem,
while in some cases we already have right amount of elements, so we can just
copy over. Further more, `BKE_key_convert_from_offset`, despite its name,
was not making any check nor allocation on keyblock's data elements!
So split 'copy' operation itself in `BKE_key_update_from_...`,
where no mem checks/operations are performed (only an assert).
Only useful in sculpt mode currently, but will be used by fix for T35170 too.
Rather straightforward, allows for 'DATA' icons (like mat or tex 'previews')
to be used as icon for operator button or items of an enum.
Patch by Simon Lušenc, with minor cleanup by self.
This can be used to avoid redundant looping when we only want to know if a list is smaller then some size.
also remove paranoid NULL check in list counting.
For FCurves where all the keyframes use the "simple" interpolation types
(i.e. Constant, Linear, and Bezier), we now use the old FCurve drawing
code that was used prior to the Easing Equations changes. This should
be generally faster in general.
When the "High Quality Line Drawing" option (View menu) is disabled,
the sampling rate (i.e. the size of timesteps to use when sampling
the FCurve for drawing it in most cases now) is set to be quite low
(i.e. at 0.1 frame increments). This amounts to at most 10 sub-steps.
In one test file (with a wide window), this had the effect of improving
the performance by over 3x. It's still not as good as a sampling-free
approach, but for this functionality is still needed for FModifiers,
so it's better that we can optimise this.
Small optimisation (which shouldn't have much of an effect) where we skip
complex handle calculations if all the handles/verts for a Bezier curve
segment are all flat.
