Not the cleanest implementation but the simplest.
This doubles the number of default shader variations.

Implicit function declaration caused by missing include
in the recent fix.

Thanks @mano-wii for finding the fix.

Also fixes the sampling of hashed shadows.

Fix the ray direction computation.
|
|
Was caused by division not giving a fully opaque alpha value.

|
|
The lines were not using the matrix to calc the tarnsformation.
|
|
Also remove historic bftgl reference.

Cast occurs first, making any flag enable this option.

When the relative mode was used, the calculation of the total number of vertices was not done and it was using the total number of vertices in the datablock. This worked for small files, but with complex files the time to allocate all the data was too long and the performance was very bad.
Now, for relative mode the real number of vertex is calculated.
Also fixed the same problem when onion and multiedit is enabled.

This was caused by 2 things: Shadow map bias and aliasing.
It made the expected depth of the shadowmap further than the surface
itself in some cases. In normal time this leads to light leaking on normal
shadow mapping but here we need to always have the shadowmap depth above
the shading point.
To fix this, we use a 5 tap inflate filter using the minimum depth of all
5 samples. Using these 5 taps, we can deduce entrance surface derivatives
and there orientation towards the light ray. We use these derivatives to
bias the depth to avoid wrong depth at depth discontinuity in the shadowmap.
This bias can lead to some shadowleaks that are less distracting than the
lightleaks it fixes.
We also add a small bias to counteract the shadowmap depth precision.

Background dithering was introduced to solve banding issues on gradient backgrounds.
This patch will enable dithering based on the texture that is used for drawing.
Only when using a GPU_RGBA8 texture the dithering will be enabled.
This disables dithering for final rendering, vertex and texture paint modes.

The onion skin was nos displayed in secondary screens when disable the Onion switch or the Overlay in the main window.
Added a check to verify if the main overlay and onion switches are enabled in any screen in order to generate the cache data.
This is required to generate the onion skin and limit the times the cache is updated because the cache is generated only in the first screen and if the first screen has the onion disabled the cache for onion skin is not generated. The loop adds time, but always is faster than regenerate the cache all the times.

Predivide all radiance components as the alpha effect comes from the hashed
transparency (pixel rejection).

Adds a check when starting blender if your platform is supported. We use a blacklist
as drivers are updated more regular then blender (stable releases).
The mechanism detects if the support level changed or has been validated by the user previously.
Changes can happen due to users updating their drivers, but also when we change the support
level in our code base.
When the user has seen the limited support level message it is saved in the user config.
It would be better to have a system specific config section, but currently not clear
what could benefit from that.
When the platform is unsupported or has limited support a dialog box will appear including a link
to our user manual describing what to do.
**Windows**
Windows uses the MessageBox that is provided by the windows kernel.
**X11**
We use a very lowlevel messagebox for X11. It is very limited in use and can be fine tuned when needed.
**SDL/APPLE**
There is no implementation for SDL or APPLE at this moment as the platform support feature targets mostly Windows users.

Before, the modifiers were evaluated in Draw Engine and this required to calculate a factor to increase the VBO size.
Now, the modifiers are evaluated in Depsgraph and the Draw Engine receives the evaluated stroke with the final number of vertices. As the number of vertices is the final value already, if Draw Manager increases the number with the modifiers only increases the memory with empty space because never would be used. This commit removes this double calculation, reducing the memory usage and removes a loop to calculate the size by modifier too.
Also, the function getDuplicationFactor() has been removed because is not required anymore.

Due the internal design of the drawing engine and the special requirements for 2D inside 3D, it's required to keep the original stroke visible in order to display the particles. If the original stroke is hidden, the particles are hidden too.
This commit only fix the segmentation fault. Make visible the particles when the original is hidden would require a complete redesign and maybe would break some 2D features.

Now the grid matrix is calculated when the shading group is created.
Also, the grid pass is only created when needed and reduce memory usage when the scene is not using grease pencil objects.

This mostly happens automatically anyway since there is usually not enough
time left over for it. But when it does it happen it breaks partial redraw,
and may also have a negative impact on responsiveness.

The first element of the loop was not calculated for all onion modes. For select mode the first selected is used, for other modes the first frame in the layer is used.

Before when Onion or Multiframe was enabled the VBO length was the total of points on the object for all frames and this results in a big size when the scene had a lot of frames.
Now, the size of VBO length is calculated more precisely and reduce the time to alloc the VBO.This also reduce memory footprint.

The flag was working in the oposite mode.

As the evaluated data is not calculated in multiframe, needs to have the original colors.

When setting an object draw type to Solid it always used the Material
color mode. This change only sets the material color when the viewport
is set to display textures.

The problem was the unit matrix was not set in the uniform variable.

This texture is used for missing textures as replace.

Make a distinction between flush sculpt changes for rendering, and forcing
sculpt data structures to be rebuilt after mesh changes. Also don't use PBVH
for renders.
