This implements a new overlay that blends the bakground color over the
objects that are not in the same mode as the active object, making
them fade with the background.
This is especially needed for sculpt mode as there is no other overlay
or indication in the viewport to display which object is active.
This is intended to be used with D7510 in order to have a faster
workflow when sculpting models with multiple objects.

This adds an option for the HDRI rotation to follow the view rotation.
When this option is enabled, this allows EEVEE materials to be used as
matcaps for sculpting and painting.
This has an extra performance cost when orbiting around the model as the
lookdev cache needs to be recalculated, but in my test it is barely
noticeable.

This new feature allows to use the strokes as an eraser of any stroke below. This is very handy to open holes in filled areas.
After running some tests, we have decided to keep the additive effect of the holdout color. To get clean holdout areas, just move the color to black to remove any additive effect. To have additive effect can be used in situations like tint slightly a transparent window with blue to simulate the glass.

When repeat image was active the image was drawn in the foreground
making most uv overlays not visible. This change creates a shared
defined value for repeating and not repeating images.
The output layout was wrong and it's a mistery why it works on most
implementations since it's clearly a wrong usage.
Thanks @sebbas for helping narrowing down the issue.
Previously, it was kind of a mess. In different places it was using `char`, `short` and `int`.
The changed properties are flags that are operated upon using bit operations. Therefore, the integer type should be unsigned. Since we only use 2 bits of these flags, `uint8_t` is large enough.
Especially note the change I had to make in `RNA_define.h` to make this work.

All the changes made in the branch `soc-2020-fluid-tools` are included in this patch.
**Major changes:**
=== Viewport Display ===
- //Raw voxel display// or //closest (nearest-neighbor)// interpolation for displaying the underlying voxel data of the simulation grids more clearly.
- An option to display //gridlines// when the slicing method is //single//.
==== Grid Display ====
- Visualization for flags, pressure and level-set representation grids with a fixed color coding based on Manta GUI.
==== Vector Display ====
- //**M**arker **A**nd **C**ell// grid visualization options for vector grids like velocity or external forces.
- Made vector display options available for external forces.
==== Coloring options for //gridlines// ====
- Range highlighting and cell filtering options for displaying the simulation grid data more precisely.
- Color gridlines with flags.
- Also, made slicing and interpolation options available for Volume Object.

The UV/Image editor was doing interpolation including over the alpha
value what makes will render incorrectly when interpolating between pure
emissive colors and pre multiplied colors. This change disabled the
interpolation.
There are some areas that don't handle pure emissive colors well. For
example erasing alpha using 2d or 3d painting. Or blurring an image in
the compositor.
This patch makes the rendering of pure emissive colors optional. In the
side panel of the Image editor it can still be enabled when needed.
There currently isn't a better place to store it as it is related on how
the image (or a layer of the image) is created. A future design needs to
make sure that the full workflow is supported.
On MacOS + Intel Iris Graphics 6100 (may affect other config too), the
texelFetch operation bypass the base mip setting of the texture object.
Using textureLod with lod = 0.0 ensure the lowest (after clamping) mip will
always be selected.
Also disable the texture filtering for this sampler to avoid unecessary
fetches.

Debug groups makes it easier to view from where an error comes from.
The backend can also implement its own callback to make it easier to
follow the API call structure in frame debuggers.
Tiled texture uses different texture structure than normal textures.
Normally we add dummy textures and use them, but I found it cleaner to
have 2 shaders and use the correct shader.
This was caused by a left over DRWPass->state modification
that made the subsequent samples redraw without Blending enabled.
This led to incorrect blending.
The fix is to use the new API for pass instancing.
This was caused by a missing state apply.
We force the GPUState to be set after the callbacks to avoid
desync between our state tracker and the real gl state.
This fixes some issues but a better general fix for all BGL would
be better.
This fix T80297 2.91 texture alpha is not transparent
This wraps the functionality used to speedup EEVEE volumetrics.
This touches the rendering code of EEVEE as it should fix a mis-usage of
the GL barrier. The barrier changed type and location, removing an
unused barrier.
In a recent update to the fluids modifier (rB03c2439d96e8), I introduced a flush call that sets all grids to NULL if the frame is outside of the allowed frame range. This way, the texture creation function must also check if the data grid is NULL before trying to create a texture.

The old image editor has an option to enable the smooth wire drawing.
This option was stored per editor and disabled by default. This patch
connects the smooth wires in the UV/Image editor to `User Prefereces ->
Viewport -> Quality -> Smooth Wire [] Overlay`.
The old option is left in place and will be removed when the old image
editor drawing code will be removed before BCon 3.
This project moves the current UV/Image editor drawing to the draw manager.
Why would we do this:
**Performance**:
Current implementation would draw each texel per time. Multiple texels could be
drawn per pixel what would overwrite the previous result. You can notice this
when working with large textures. Repeat image drawing made this visible by
drawing for a small period of time and stop drawing the rest. Now the rendering
is fast and all repeated images are drawn.
**Alpha drawing**:
Current implementation would draw directly in display space. Giving incorrect
results when displaying alpha transparent images.
This addresses {T52680}, {T74709}, {T79518}
The image editor now can show emission only colors. See {D8234} for
examples.
**Current Limitations**
Using images that are larger than supported by your GPU are resized (eg larger
than 16000x16000 are resized to 8k). This leaves some blurring artifacts. It is
a low priority to add support back of displaying individual pixels of huge
images. There is a design task {T80113} with more detail.
**Implementation overview**
Introduced an Image Engine in the draw module. this engine is responsible for
drawing the texture in the main area of the UV/Image editor. The overlay engine
has a edit_uv overlay which is responsible to draw the UV's, shadows and
overlays specifically for the UV Image editor. The background + checker pattern
is drawn by the overlay_background.
The patch will allow us to share overlays between the 3d viewport and UV/Image
editor more easily. In most cases we just need to switch the `pos` with the `u`
attribute in the vertex shader.
The project can be activated in the user preferences as experimental features.
In a later commit this will be reversed.
