createOffscreenContext left the new context bound to the calling thread
causing a race condition with the background thread doing the actual
rendering. see T55555 for a more detailed description of the problem.
this patch changes the behavior of createOffscreenContext to restore the
context to the calling context.

rBe0c088f8fb5a introduced offline rendering support on windows, sadly it was trying to use the desktop window for getting a context, which given SetPixelFormat can only be called once for any given HDC was an unfortunate choice.
This patch uses a temporary hidden window for getting the opengl context.

This reverts commit 7529690df38ced314d59af3b10c610e3fd56c807.
I tried to put manually add threading protection to GHOST around
Xlib calls but that did not fix the crashes. So reverting that
for now despite the performance implication on some system.

This was needed because we were sharing opengl contexts across multiple
threads. With the recent refactor this should be no longer needed.
|
|
Was causing crash on startup.

Same as 128926a41b368e166af63515370d9c9367e3dda2 but for windows.

This way they can be init in their owner thread. Contexts should not be
shared accross threads. Once you make a context active on a thread it is
owned by the thread.
This commit only have the GLX backend updated but should not break orther
platform.

Harmless since this is always enabled,
only do this for easier troubleshooting when disabling the define.

This means we can check keys such as tilde in a generic way.

This still uses the correct string when typing text,
it just allows the key to be used in keymaps.
We should eventually add scan-code support.

All keyboard events were sending double key events (including modifiers)
when xinput was enabled with gnome (causing much confusion!).
I cant test if XIM works,
but this isn't useful to send double events, so disabling for now.

Need to compare, NOT to override passed file name.

When creating an offscreen context we need wglCreatePbufferARB to create
a drawable. In non-background mode wglCreatePbufferARB would have been set
by the main window creation code. But in background mode this is not the
case so we need to create a dummy context using the screen window to init
wglew properly.
|
|
For some reason this happened if no windows are created before creating an
offscreen context.

window is hidden.

Use Blender native dialog when OS dialog's aren't supported.

Unity itself is deprecated, but the API is also supported by KDE and the GNOME Dock extension,
which means that it will be useful for a wide variety of distributions.
To get a progress bar, the system must have a blender.desktop file and libunity installed.
The need for libunity is annoying, but the only alternative would be to integrate a DBus library...

Offscreen contexts are not attached to a window and can only be used for rendering to frambuffer objects.

GLX implementation : Clément Foucault (fclem)
WGL implementation : Germano Cavalcante (mano-wii)
Other implementation are just place holder for now.

Instead of cloning the window to create dummyHWNDs and dummyHDCs to avoid calling the SetPixelFormat more than once in the same window, use the original window and HDC and do not call the SetPixelFormat again.
In addition to avoiding a lot of unnecessary calls, it simplifies the code and makes it match the others OS

There is currently a limitation in XWayland,
the cursor needs to be hidden during warp calls.
