we cant ensure that a requested buffer can be allocated so report opengl errors when failing to allocate the buffer (rather then printing to console).
this is common enough and generic error isn't too helpful to users.
The bug was 'write_still' was incorrectly being initialized to 'view_context'.
'write_still' should always write an image, so failing silently here is bad behavior.
Also, opengl render and internal render engine operator should use this option the same way.
- OpenGL still render failed when output format was set to Movie.
Now it just doesn't save a file and renders anyway.
- Bone heat weight was missing 'wait cursor'.
- Waitcursor for Mac Cocoa is back! Made all OS's use the same
nice hourglass cursor.
(Note: this violates Mac UI guidelines, we should rely on the
spinning wheel of death instead. Highly disputable that.)
OpenGL viewport render gave squeezed results in cases.
Reason: some graphics cards only give offscreen buffers in multiples
of 256 or 512 (my case).
Current fix uses the actual size returned by graphics card, which
is also safe for too large renders.
More elaborate cropping or matching is for another time.
(Added printf for feedback on this, might disappear)
The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.
Also made some 'char *' args into 'const char *'
the render engine assumes the RenderResult's rectf is not in linear color space when color management is disabled so the sequencer and opengl render need to follow this else it results in dark images.
When enabled the context's 3D view will be used for rendering.
When disabled a camera view with solid draw mode will be used.
(Needed for batch rendering out animation previews without having to worry about an existing 3D view, its local layer locking and draw type)
Only source/blender/editors/ dir, should not give errors on different platforms
Only removing: UI_*.h, ED_*.h, WM_*.h, DNA_*.h, IMB_*.h, RNA_*.h, PIL_*.h
unrelated changes that ended up being more trouble to commit separate...
- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile
- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
