This commit adds a new command line argument --debug-ghost and
makes it so X11 errors happening during context initialization
are only printed when this new flag is sued.
There is no need to flood users with errors when their GPU is
not supporting latest OpenGL version. Or, at a very minimum,
the error must be more meaning full.

In order to recover from a transient Focus Out - Focus In disruption
in the middle of a shortcut, which can be caused by certain window
managers, Blender has code that checks which modifier keys are pressed
after Focus In and restores the modifier state based on that.
If one of the Ctrl, Shift, Alt, Super keys is not mapped anywhere
in the active keyboard layout, XKeysymToKeycode returns the invalid
zero keycode, and reading the key state produces garbage, which can
cause an invalid modifier state. Check the return value to avoid this.

`WS_CHILD` is a different kind of child window that what we define as
child window. See http://forums.codeguru.com/showthread.php?491604.
Setting this style flag seems to mess things up a bit in our
configuration. The name bar is actually being overlapped by the Windows
task bar then. Not totally sure why this happens, but I think it's
because windows with the `WS_CHILD` style are positioned relative to the
parent, not the desktop (screen without taskbar). So it uses the full
space available when maximized, which isn't clipped by the taskbar
anymore.

When using OpenCL with Cycles the rendering time increased substantial.
After doing some tests the bottleneck was found in 4d voronoi and 2d and
3d smooth voronoi.
This change will hide these behind a specific compile directive so the
speed will improve.

2.80 (3:10)
2.81 (5:48)
2.81 excluding 4d voronoi+2d/3d smooth (3:50)

This change switches windows to the dynamic C runtime
avoiding issues coming from mixing the static and dynamic
runtime like the ones outlined in [1]

Pointer used for math arithmetics in assert().
CUDA device pointer is actually an integer type, not a pointer.

The multi device code did not correctly handle cases where some GPUs store a
resource in device memory and others store it in host mapped memory.

Cycles did not update the "is_enabled" flag on lights when they were synchronized again, which caused all lights disabled by "LightManager::disable_ineffective_light" to be disabled indefinitely. As a result the OptiX kernels were not reloaded with correct features when a change to a light was made. This fixes that by updating the "is_enabled" flag during synchronization.

The cryptomatte sockets were incorrectly numbered using a step size of two. While the increment by two is necessary to get the correct number of render passes, they should be numbered consecutively matching the socket names of the cryptomatte node.

The idea is to give multiple coordinates to evaluator and evaluate them
all at once, avoiding any possible overhead.
|
|
Allows to pass multiple patch coordinates for evaluation.
|
|
Saves another unnecessary temporary data copy during evaluation.
|
|
Consider that all builders have face-varying evaluation now.
|
|
|
|
Make evaluator itself to write directly to the output buffer.
Brings unmeasurable speedup and makes it possible to simplify
some buffer class logic.
|
|
We currently don't support interleaved varying data, so can make
some buffer smaller.

This brings the behavior in line with Windows and Linux. Going between
multiple windows now doesn't use the first click only to change focus
but also allows Blender to process those events.

Was caused by D6068, which did not handle "MEM_PIXELS" memory
when not in background mode. Before that it always fell back to using
generic device memory, so restoring that behavior. In future this
should be changes to use OpenGL interop for optimal performance.

with CUDA
The OptiX implementation wasn't trying to allocate memory on the host if device allocation failed, while the CUDA implementation did. This copies the implementation over to OptiX to remedy that.

This is intended for developers on Windows primarily:
Now, CUDA architectures of type compute_xx are supported. This allows for quicker builds,
at the expense of the CUDA driver running ptxas the first time a kernel is loaded.
