While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Use to avoid accidental missing break statements,
use ATTR_FALLTHROUGH to suppress.

MX (Multiple conteXt) support was dropped from the GLEW 2.0 library to make core profile support cleaner.
Our WITH_GLEW_MX build option was OFF by default already; this commit removes the inactive code paths.
I'm working on a plan for multiple GPUs, contexts, resource sharing, etc. This commit gives us a cleaner starting point for that upcoming work.
Tested on Mac, will test on Linux & Windows immediately after pushing.

ifdef out most debugging code since Apple does not implement any debug extensions. We can revisit this if they ever do (don't expect that).
Changed output message so Mac users don't think --debug-gpu is broken.

This extension is the best we have on some older supported GPU + OS combinations.
All the code was in place, just disabled.
|
|
I was removing deprecated/obsolete state from this function. About halfway through I started questioning the need for the whole thing.
GPU_state_print is not called anywhere, but is (was) available as a development aid.
External GL debugging tools are really good these days! We should use those to examine state & not roll our own.

Drop SciTech support & workarounds for WinCE and OpenGL ES.
AMD_debug_output is still in the code but disabled. Once I verify the newer extensions are available on all the GPU + OS combos we support we can delete this disabled code.
|

Errors are caught & reported by our GL debug callback. This gives us way more useful information than sporadic calls to glGetError.
I removed almost all use of glGetError, including our own GPU_ASSERT_NO_GL_ERRORS and GPU_CHECK_ERRORS_AROUND macros.
Still used in rna_Image_gl_load because it passes unvalidated input to OpenGL functions.
Still used in gpu_state_print_fl_ex as an exception handling hack -- will rewrite this soon.
The optimism embodied by this commit will not prevent OpenGL errors. We need to analyze what would cause GL to fail at certain points and proactively intercept these failures. Or guarantee they can't happen.

Can now build release and debug.
Close to final version in master (which took several commits).

Reduces noise from --debug-gpu so we can spot serious errors.
Blender 2.7x uses OpenGL 2.1, we don't care if features are deprecated.
I'll re-enable these warnings for blender2.8 after next merge.

Backtrace so we can pinpoint where the GL error came from. Then fflush
on severe errors in case it's severe enough to crash Blender.

When running blender --debug-gpu
Display which debug facilities are available. One of these, in order of preference:
- OpenGL 4.3
- KHR_debug
- ARB_debug_output
- AMD_debug_output
All messages are logged now, not just errors. Will probably turn some of these off later.
GL_DEBUG_OUTPUT_SYNCHRONOUS lets us break on errors and backtrace to the exact trouble spot.
Callers of GPU_string_marker no longer pass in a message length, just the message itself (null terminated).
Apple provides no GL debug logging features.

Also use gcc style file:line: syntax for errors.

stderr was getting flooded with too many error messages, most of which
were not really relevant.

option.
This makes sense, since contexts get created at runtime, there is little
reason to require recompilation for this.
Only works on linux currently, will be doing more OSs later

Is pretty much what it says :)
Easy subtitles for everyone!
Supports size, positioning,
a cheap shadow effect (probably will need more work),
and autocentering on x axis.
Now you can go wild with long spanish names
in your soap opera videos.
Will probably be refined as days go by,
but at least it's now ready for testing.

Enable debug output in debug contexts for gl 4.3+

patch number D706 with changes:
- WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging
system functions) but leaves the checks we had intact. Old patch
added the debug functionality only if we had the flag on to save some
performance.
Rationale here is that we might not want to recompile blender just to get
the extra information, and having users start blender with a -d flag to
get the extra information is also useful for bug reports. Those checks already
existed and most expensive ones are hidden behind a debug mode check
so performance should not be that bad.
- Did some cleanup of existing functionality:
When things go wrong blender side, just print the error,
don't check for GL errors first.
- Did not port changes needed for GLES to regular glew.h
- Got rid of duplicate or very similar new functionality.
Generally, code is more moving things around/cleanup and should work exactly
as before apart from the debug context, so it's safe to add even now.
It also provides a nice substitute function for glu error descriptions
