Cycles: Fix building of OpenCL kernels

Theres no overloading of functions in OpenCL so we can't make use of
`safe_normalize` with `float2`.

Add filtering for UI elements

There is a remaining preset drawing issue that needs resolving.

BGE: 2D filter additions.

gpu_draw: skip color management for textures declared as 'non-color'.

New reserved names in 2D filters: bgl_ObjectTextureX (X=0 to 4) to
access texture channels 0 to 4 of the object on which the 2D filter
is defined.

Force U.use_16bit_textures to 1 in the blender player to give access to
floating point textures in the 2D fitlers shaders.

bge.logic.setOffScreen(True) to define and use a floating point offscreen
render buffer of the same size than the framebuffer in the main BGE loop.
Useful to get floating point results from 2D filters. The offscreen render
buffer will automatically be used by bge.texture.ImageViewport if it's enabled.
It is legal to call bge.logic.setOffScreen(True/False) to disable and reenable
the framebuffer on a frame by frame basis.

New refresh mode for bge.texture.ImageViewport and bge.texture.ImageRender
objects:
iv.refresh(buffer, mode)
mode = "DEPTH" to retrieve floating point depth buffer
= "RG32F" to retrieve red and green channels as floating point.
= "RGB32F" to retrieve red, green and blue channels as floating point
= "RGBA32F" to retrieve red, green, blue and alpha channels as floating point.
For ImageViewport and ImageRender, refresh() bypasses all filters and object
options and retrieve directly from the frame buffer or render buffer.

Use blank string for default template

Fix T51012: Surface modifier was not working with curves

This prevented the Force Field Curve Shape of working

Disable template before addons

So we don't attempt to disable addons twice

Addon support enable/disable now works

Add simple addon as a demo

Layers: Remove old base visible / selected code

Attempt to fix selection code (not working though)

Adding missing DAG_relations_tag_update

Blender 2.8: Initial hook of layer collections evaluation in DEG

This moves selectability/visibility flag flush from some hardcoded
places in the code to depsgraph. This way it is possible to simply
tag depsgraph to update those flags and rest it'll do on it's own.

Using depsgraph for such flush is an overkill: those flags are fully
static and can not be animated, so it doesn't really make sense to
hook only those to depsgraph.

However, in the future we will have overrides on collections, which
ideally would need to be animatable and drivable and easiest way
to support this is to do this on depsgraph level, so it ensures
proper order of evaluation for animation and drivers. And it seems
logical to do both overrides and flags flush from depsgraph from
this point of view.

This commit lacks two things:

1. Proper flag for DAG_id_tag_update(), so currently the only way
to inform depsgraph about nered to flush visiblity/selectability
flags is to tag scene ID for update. Flag of 0 will to the trick
for now.

2. Any operation which changes layer collections or render layers
need to tag relations to update. This is not done, so any change
to those will cause crash.

Layers / Depsgraph: Unittesting for selection and visibility evaluation

added ids to all grids, vars, funcs, etc in manta scripts

having unique python variables allows having multiple domains in the viewport at once

Fix T50268: Cycles allows to select un supported GPUs for OpenCL

Cycles: Update remaining time once per second without waiting for a tile change

Previously, the code would only update the status string if the main status changed.
However, the main status did not include the remaining time, and therefore it wasn't updated until the amount of rendered tiles (which is part of the main status) changed.

This commit therefore makes the BlenderSession remember the time of the last status update and forces a status update if the last one was more than a second ago.

Reviewers: sergey

Differential Revision: https://developer.blender.org/D2465

Edit Mode Engine: Remove unecessary matrix.

Object Mode Engine: New outline method.

We render selected meshes into another buffer and use a screen space shader to expand the color out of the mesh silouhette.

Pros: only one additionnal render pass is needed (like old outline code), and we have occluded informations.
Cons: memory usage is a problem. This method needs 2 color buffer to ping pong when expanding the outline and 1 depth buffer to test occluded fragments. This gives a 88 bits/pix memory footprint.

Idea: Since we don't need all color range but only some uniform colors (theme colors) we could manipulate only the color ID instead of the whole color this could cut the color buffer size and lower the memory footprint to 58 bits/pix.

Draw module: code style, encapsulate static vars

Fix T50975: Cycles: Light sampling threshold inadvertently clamps negative lamps

Cleanup: remove useless `glDisable(GL_LINE_STIPPLE)` call.

Note that muted strips have solid border currently, marked as TODO to
add back stippled lines (if with want them back?).
