Changed a way how RGB images are saving from RGBA

Before alpha channel was simply ignored causing bad looking
straight colors which is pretty much useless.

Now saving RGB would alpha-over image on top of black color,
which makes final image look really nice. It's also very
such the same what other graphics software does this.

In the future we could easily support configurable backdrop
color, which would be really the same as other SW does it.

Also, it'll probably worth adding the same mode to RGB
display of image editor.

Draw a checker board as a background for animation player

This makes it easier and useful to investigate alpha channels,
without this straight colors are displayed on the screen which
are completely useless in case of player.

Fix sequencer crash when pasteing strips after creating new file

Issue happened for scene. movie clip and mask strips, which contains
pointers to datablocks which are freeing on loading new file.

Also, scene strip would crash when pasted from clipboard after scene
was unlinked from file.

Fix memory leak when loading multilayer EXR as movie clip

Such kind of image sequences wouldn't be displayed still
and supporting them would take some additional time, but
for now it'll be no memory leak on attempt opening such
images.

Remove unused rigid registration code

There're some features planned which would
require rigid registration, but this code
would need to be re-done anyway to use new
minimizer and solving some issues with ICP
algorithm there.

Modal (aka tripod) solver rework

Several major things are done in this commit:

- First of all, logic of modal solver was changed.
We do not rely on only minimizer to take care of
guessing rotation for frame, but we're using
analytical rotation computation for point clouds
to obtain initial rotation.

Then this rotation is being refined using Ceres
minimizer and now instead of minimizing average
distance between points of point of two clouds,
minimization of reprojection error of point
cloud onto frame happens.

This gives quite a bit of precision improvement.

- Second bigger improvement here is using bundle
adjustment for a result of first step when we're
only estimating rotation between neighbor images
and reprojecting markers.

This averages error across the image sequence
avoiding error accumulation. Also, this will
tweak bundles themselves a bit for better match.

- And last bigger improvement here is support of
camera intrinsics refirenment.

This allowed to significantly improve solution
for real-life footage and results after such
refining are much more usable than it were before.

Thanks to Keir for the help and code review.

Increase verbosity level for reprojected markers info

This information is useful, but in cases when you, say,
working on a bundler it's annoying to scroll all the
information up.

Now behavior would be:
- running `./blender --debug-libmv` will print all the
debug messages
- running `./blender --debug-libmv --verbose 0` will
print only debug messages from solvers, recosntruction
and so, but will bypass final reprojection bunch of
messages
- running `./blender --debug-lib,v --verbose 1` will
include final reprojection messages.

Move radial distortion code to own templated function

This shall not lead to any functional changes, just
avoids radial distortion code duplicated in camera
intrinsics and bundling code.

For fancier bundle adjustment supprting different
distortion models this is not actually enough and
would need to make some bigger changes, but this
changes makes code a bit easier to maintain already.

fix [#33466] alt + mouse wheel

Alt+Mouse Wheel events depended on the button under the mouse being active, else it would change the current frame.
Button re-activation wasn't 100% reliable since it depends on fake mousemove events.

Now keep button active when its executed if the mouse stays over it.

fix for harmless glitch rotating the camera in camera mode, having the center point so close to the viewpoint caused the helper line to erratically move about because of float precision.

LocDiff Driver Vars: Red-Alert is not needed on the space-selectors

Bugfix: Invalid target tagging for "Distance" driver variable type only
highlighted the first target if/when both targets were empty.

Bugfix: Types mismatch (flags and targetFlags were ints, but dtar->flag is a
short)

Invalid Driver Targets are now indicated appropriately (using Red Backgrounds)
in the UI

This is the second part of the fixes for [#32492], making it easier to identify
which part of a driver (i.e. which of its targets) is causing problems

A number of additional/related changes needed to be made:
* Red-alert status for layouts is now propagated down to child layouts when they
are created. This is needed as otherwise some of the templates used in the Graph
Editor driver settings won't actually get the red-alert status flushed down to
them. Also, note that this status needs to be set before any widgets are added
to the layout, or else the settings aren't applied when the relevant widgets get
created.

* "Single Property" RNA-Paths resulting in out of bounds array access will now
trigger an error status and appropriate warnings

TODO:
* The error tagging doesn't get applied immediately after variables are created,
or their types changed
* There was also some other weirdness involved when a higher-value flag (1<<10)
was used for this setting, which needs further attention

fix [#34426] Manipulator handles drawn incorrectly by depth
original patch by Philipp Oeser (lichtwerk) with own changes.

rst doc update: adding a link to Joystick class from bge.logic.joysticks
(so one can find more about the joystick class without having to search joystick)
code untested by the way. Sorry but I can no longer build sphinx docs here. I will try to fix that later.

fix for bmesh regression similar to last revision r54920. only effected loading old blend files without edge data.

fix for regression since BMesh merge, selecting linked faces in face-mask mode was using an incorrect lookup on loops which made select-linked fail

code cleanup: includes

fix for linking with recent armature refactor, was also missing file from CMakeLists.txt.
