Fix T47168: Project image looses float precision

Doc: more detailed ImBuf.rect/rect_float comments

Cleanup: warning, whitespace

Improve multi-paint tip

Usual fixes and tweaks for UI messages.

Fix broken i18n messages extracting script with new py code.

Some py devs are way too smart for our own good... :P

Cycles: One more attempt to fix issue mentioned in previous commit

Cycles: Fix typo in the debug panel commit

Cycles: Fix string compiler warnings after recent changes

Cycles: Cleanup, spelling and indentation

Cycles: Remove the experimental CUDA kernel.

This commit removes the experimental CUDA kernel, making SSS and CMJ
regular features.

Several improvements have been made in the past few
weeks (thanks Sergey!) which make SSS render several times faster (2-3x
compared to 2.76b) on the GPU, and the increased VRAM usage has also been
fixed. Therefore the experimental kernel is no longer needed.

Manual has been updated: too:

Compositor: Add option to extend image bounds when blurring

It is handy when doing some roto work and it's required to blur some
mask or overaly before alpha-overing it on top of the footage.

Quite straightforward option with the only limitation that variable
size blur is not supported.

Libmv: Solve strict compiler warnings in stubs

Add compression modes for TIFF images

This patch aims at providing multiple compression modes for TIFF output,
particularly uncompressed mode.

At this moment have None, Deflate, LZW and Pack Bits modes been integrated,
mimicking The GIMP export modes (except JPEG mode, which returned encoding
errors).

More modes could be added if needed.

Default remains Deflate.

Cycles: Tweak inline policy for some functions

The goal is to make Experimental kernel closer in performance to the
official kernel, avoiding spills and such.

There should not be big impact on official kernel, own tests showed
few percent performance drop on laptop's GPU. CPU was always the
same speed on AVX, AVX2 and SSE4.1 CPUs i've been testing here.

This seems to be the last essential step before we can get rid of
Experimental kernel and enable SSS officially on GPU without causing
some major performance issues.

Surely some more tweaks are possibly required, but that we can do
for until cows go home anyway.

Cycles: Reduce scope of some defines set in CMakeLists

Should be no functional changes at all, just speeds up re-compilation
when some features needs to be disabled for development purposes.

For example, when running lots of Valgrind it's handy to disable any
GPU devices because otherwise you'll be wasting quite some time in
the driver while enumerating devices.

Fix typo in image editor grease pencil panel

CMake: Silence messages about unordered map and shared pointer on second run

This variables are being cached anyway and can only be changed on first run,
no need to keep reporting them again and again.

Fix image save ignoring options

Saving an image didn't un-set previously enabled options.
(saving 16bit png as 8 bit didn't work for eg).
