Basically the framebuffer size was different from the glViewport size.
This made the depth read in glReadPixel not corresponding to the center of the pixel.
Another thing that reduced precision compared to blender 2.79 is the `GPU_matrix_unproject` that now computes using `float`s instead of `double`s.
But this may be for another commit.
Due to recent changes the AA was not rendered in the viewport when not
interacting. When interacting it was. This was due to incorrect
detemination to perform TAA.
Create a new pass for them and draw them separately.
Beware of the double multisample resolve when multi-editing a mix of curves
with and without the "in front" option enabled.
This patch adds a new "Use Alpha" option on image empties to avoid ordering
issue of reference images.
If ordering is not important, "Use Alpha" can be enabled to provide
transparency and alpha blending support.
Finding visible connected elements is often a direct lookup
when they're not connected to hidden geometry.
Add inline wrappers that avoid a function call,
gives minor speedup creating GPU edit-mesh data.
When Specular Transparent materials are used the world clipping
did not work on the transparent materials. The reason was that the
accum shaders did not vary on the existance of the clipping planes
This patch will variate the accum shaders when clipping planes are
active.

Workbench render engine did not work when an odd number of AA samples
were used. A user could enter these values by disabling AA or set the
number of AA samples in the Render/Film panel to an odd number.
This commit will not perform TAA passes when AA is disabled.
For supporting the setting of 5 or 11 samples the bitmask was replaced
by an if statement as this was making the odd number not render
correctly.
As extra introduce the jitter samples of 5 and 11 so the images will
be more clean. a jitter sample of 11 used to read outside the allocated
space of the jitter samples.

When using LookDev in Quad view the cache was only updated for the first
Q-view. The evaluation data of the last cache was not stored with the
lightprobe textures. As the evaluation data was reused between the
Q-views only the lightprobe textures of the first view was updated.
With this patch the evaluated data is stored amongside the actual
lightprobe textures.

Was due to incorrect output size. Use engine->resolution_x/y instead of
computing the size on the fly from the scene specific settings (which are
not overwritten by the rendering scene).
This commit groups several options that were tested in grease pencil branch:
- Changes to fill algorithms and improves, specially in small areas and stroke corners.
New options has been added in order to define how the fill is working and internally there are optimizations in detect the small areas in the extremes.
Kudos to @charlie for coding this fill improvements.
- New 3D cursor view plane option.
Now it's possible to lock the drawing plane to the 3D cursor and use the 3D cursor orientation. This allows more flexibility when you are drawing and reduce the need to create geometry to draw over surfaces.
- Canvas Grid now can be locked to 3D cursor.
- New option to reproject stroke using 3D cursor.
- Small tweaks and fixes.

The shaders are: `GPU_SHADER_3D_FLAT_SELECT_ID` and `GPU_SHADER_3D_UNIFORM_SELECT_ID`.
This commit allows the drawing of the mesh select ids to be done on a 32UI format texture.
This simplifies the shader that previously acted on the backbuffer and had to do an uint to rgba conversion.

Enable depth picking by default.
This adds new 'gpu_flag' since it's not so relevant to add GPU drawing
options into uiflag & uiflag2.
This resets the recently added smooth edge flag.
Invert the texture of the stroke if the random UV is activated. Before, this parameter only affected to dot mode, but not to line strokes.
The texture is inverted vertically.
This fix saves the camera matrices in order to not call
BKE_animsys_evaluate_animdata during each draw loop. This function tags
the view as dirty even if the camera does not move.
This effectivly, avoids the constant reset of TAA.
Draw manager was checking for particles being enabled in viewport, but
actual evaluation was happening for render. Now the check in draw manager
properly follows current evaluation mode.
Additionally, de-duplicated some check, by moving everything needed to
a single place.
Annoying part is the const-cast, that could be cleaned up later by
modifying some underlying functions.
