Although the normal was normalized when evaluating the lighting, the normal
is often used for other purpose. In this case using the non normalized
normal maybe the source of errors.
This is a nasty bug. Because the node does not get properlly tagged as SSS
(sss_id is 0) but is still evaluated (so tagging the GPUMaterial as having
SSS). The sssProfile UBO is still declared and we need to bind something
to it.
On some platform does not support line width > 1.0 and can even throw and
error. Better check an at least display something rather than no lines at
all.
Node group inputs should behave like cycles now.
----
We create dummy nodes that contains the default values for the nodegroup
inputs and link them to the sockets. This way the uniform buffer gathering
function can read them.
But we also need to disconnect all the internal links to sockets that have
hidden values. Theses sockets must not get the values from the nodegroup
input sockets if there is no link to them otherwise we get broken results
(i.e.: normals for a bsdf node).
With the new automatic handle algorithm, it is possible to do a lot
of the animation via keyframes without touching the curves. It is
however necessary to change the keyframe interpolation and handle
types in certain cases. Currently the dopesheet/action editor
allows changing the types, but does not show them in any way.
To fix, add a new menu option to display this information. For handle
type, it is represented using the shape of the key icons: diamond for
Free, clipped diamond for Aligned, square for Vector, circle for Auto
Clamp, and cirle with dot for Automatic.
Non-bezier interpolation is a property of intervals between keys,
so it is marked by drawing lines, similar to holds. In this initial
version, only the fact of non-bezier interpolation is displayed,
without distinguishing types. For summaries, the line is drawn at
half alpha if not all curves in the group are non-bezier.
In addition, it is sometimes helpful to know the general direction
of change of the curve, and which keys are extremes. This commit
also adds an option to highlight extremes, based on comparing the
keyed values with adjacent keys. Half-intensity display is used
for overshot bezier extremes, or non-uniform summaries.

Adding a workaround in this case: we blit the depth buffer instead of the
stencil buffer and use the copy as the texture. This is slower but at
least it should work.
When calling glBlitFramebuffer on most (if not all) mac that have a GPU
from the Radeon Pro series, the data is not properly copied and only a
subset of the pixels are correctly copied.
This only happens when blitting the depth buffer if the depth buffer is
GL_DEPTH24_STENCIL8.
Changing the depth buffer format to GPU_DEPTH32F_STENCIL8 fixes the issue
but only works if blitting the depth componnent. The stencil componnent
still provoke issues when being copied.
This is caused by a driver bug that prevent us from rendering to (or even
binding) a texture mip level that is below GL_TEXTURE_MAX_LEVEL of the
target texture. This is fine in most drivers (and legal AFAIK) but not on
thoses Intels HDXXX + Windows.
As a fix we just put GL_TEXTURE_MAX_LEVEL lower (which is illegal because
it is undefined behaviour), but in practice it works ok and does not
trigger any warnings or errors.
This commit fixes most of the problems encountered on these GPUs (T56668).
At least on windows we do not re-run datatoc when the .glsl files change.
To test is simple, just change edit_mesh_overlay_common_lib.glsl
remove lines, write plain text, ..., now rebuild and go in edit mode
with the default cube.
I also had to remove the entry in gpu/CMakeLists.txt for
gpu_shader_material.glsl since this was being tracked directly, as well
as running data_to_c_simple (otherwise CMake raises an error for
duplicated entries).
We probably want to do the same for the other datatoc functions.

The appearance is a bit different than 2.79 where the flame was just added
on top of the smoke without correct blending.
Now it's much more realistic and using volumetric integration. You can see
the smoke actually masking the flame.
The other difference is that the flame color was not using proper color
managed blending. Now with the use of filmic it shows bright yellow.
This could be adjusted and displayed as a user parameter in the future.
Includes the following fixes
- Fix smoke texture creation: data was interpreted as Byte instead of Floats.
- Fix Velocity texture not being free after draw: also was causing crashes.
- Fix display_thickness not being copied during COW.
- Fix Blending and general volume rendering algorithm.
- Add Volume Shadowing support.
NOTE: This commit only concern edit UVs and not the "shadow" mesh displayed
when texture painting. This will be address in a future commit.
We now cache the uv mesh in the mesh batch cache and only reupload data on
changes.
Update could be more granular (and a bit faster) but it's not our main
concern ATM.
This should fix problem caused by the IMM api used to draw large meshes.
This makes performance skyrocket compared to previous implementation.
There is still a big CPU bottleneck when not in sync selection mode but it
is not related to the drawing function directly.
