Stuff like automake stuff is no longer used, as well as a number of
other files that are no longer in use.
Also fixed cmbuild/ and build/ to /cmbuild/ and /build/ to emphasize
that they're fot root-level. Not that they'll ever be used recursively,
but still.
- Changed glMapBuffer to glMapBufferRange to allow invalidation. Using
just glMapBuffer alone was causing some unacceptable stalls.
- Changed dynamic buffers from GL_DYNAMIC_WRITE to GL_STREAM_WRITE
because I had misunderstood the OpenGL specification
- Added _OPENGL and _D3D11 builtin preprocessor macros to effects to
allow special processing if needed
- Added fmod support to shaders (NOTE: D3D and GL do not function
identically with negative numbers when using this. Positive numbers
however function identically)
- Created a planar conversion shader that converts from packed YUV to
planar 420 right on the GPU without any CPU processing. Reduces
required GPU download size to approximately 37.5% of its normal rate
as well. GPU usage down by 10 entire percentage points despite the
extra required pass.

Notes and details
--------------------------------------------------
Why was this done? Because wxWidgets was just lacking in many areas. I
know wxWidgets is designed to be used with native controls, and that's
great, but wxWidgets just is not a feature-complete toolkit for
multiplatform applications. It lacks in dialog editors, its code is
archaic and outdated, and I just feel frustrated every time I try to do
things with it.
Qt on the other hand.. I had to actually try Qt to realize how much
better it was as a toolkit. They've got everything from dialog editors,
to an IDE, a debugger, build tools, just everything, and it's all
top-notch and highly maintained. The focus of the toolkit is
application development, and they spend their time trying to help
people do exactly that: make programs. Great support, great tools,
and because of that, great toolkit. I just didn't want to alienate any
developers by being stubborn about native widgets.
There *are* some things that are rather lackluster about it and design
choices I disagree with though. For example, I realize that to have an
easy to use toolkit you have to have some level of code generation.
However, in my personal and humble opinion, moc just feels like a
terrible way to approach the problem. Even now I feel like there are a
variety of ways you could handle code generation and automatic
management of things like that. I don't like the idea of circumventing
the language itself like that. It feels like one giant massive hack.
--------------------------------------------------
Things that aren't working properly:
--------------------------------------------------
- Settings dialog is not implemented. The dialog is complete but the
code to handle the dialog hasn't been constructed yet.
- There is a problem with using Qt widgets as a device target on
windows, with at least OpenGL: if I have the preview widget
automatically resize itself, it seems to cause some sort of video
card failure that I don't understand.
- Because of the above, resizing the preview widget has been disabled
until I can figure out what's going on, so it's currently only a
32x32 area.
- Direct3D doesn't seem to render correctly either, seems that the
viewport is messed up or something. I'm sort of confused about
what's going on with it.
- The new main window seems to be triggering more race conditions than
the wxWidgets main window dialog did. I'm not entirely sure what's
going on here, but this may just be existing race conditions within
libobs itself that I just never spotted before (even though I tend to
be very thorough with race conditions any time I use variables
cross-thread)
