jp9000 41fad2d1a4 (API Change) Use const params where applicable
This Fixes a minor flaw with the API where data had to always be mutable
to be usable by the API.

Functions that do not modify the fundamental underlying data of a
structure should be marked as constant, both for safety and to signify
that the parameter is input only and will not be modified by the
function using it.

jp9000 c9df41c1e2 (API Change) Remove pointers from all typedefs
Typedef pointers are unsafe.  If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data.  I admit this was a fundamental mistake that must
be corrected.

All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.

This does not break ABI though, which is pretty nice.

jp9000 3967c6354a Replace ARB_separate_shader_objects extension
This replaces the ARB_separate_shader_objects extension with traditional
linked shaders.  I was able to get the existing system to use linked
shaders without having to change any libobs graphics API.

This essentially creates a linked list of shader programs with
references to the shaders they link.  Before draw, it searches that
linked list for a particular pixel/vertex shader pair, and the linked
program associated with it.  If no matching program exists, it creates
the program.

jp9000 5780f3f177 (API Change) Improve graphics API consistency
Summary:
- Prefix all graphics subsystem names with gs_ or GS_
- Unsquish funciton names (for example _setfloat to _set_float)
- Changed create functions to be more consistent with the rest of the
  API elsewhere.  For exmaple, instead of
  gs_create_texture/gs_texture_destroy, it's now
  gs_texture_create/gs_texture_destroy
- Renamed gs_stencil_op enum to gs_stencil_op_type

jp9000 778cc2b318 (API Change) obs_reset_video: Use return codes
Changed API functions:
libobs: obs_reset_video

Before, video initialization returned a boolean, but "failed" is too
little information, if it fails due to lack of device capabilities or
bad video device parameters, the front-end needs to know that.

The OBS Basic UI has also been updated to reflect this API change.

NOTE: In texture_setimage, I had to move variables to the top of the

'illegal use of this type as an expression'.

To sum it up, microsoft's C compiler is still utter garbage.

jp9000 27010a2f56 Add a 'flush' command to graphics subsystem
...I'm actually concerned that I went a bit overkill trying to prevent
backwards compatibility issues with this abstraction design, because
this is a large number of files that have to be modified just to add a
single graphics subsystem export.  Someone's going to strangle me, and
when you know that someone might strangle you, that means that you did
something wrong.  We'll have to look in to simplifying this in the
future without killing backward compatibility safety.

jp9000 8aa49cc9ad Remove unused graphics subsystem functions
These functions were mostly related to being able to set true fullscreen
mode -- however, this has no place for our purposes, and these functions
were just sitting empty and unused, so they should be removed.

Besides, fullscreen mode only applies to the windows operating system.

jp9000 f4e7a893c5 Remove 'rebuild' variable from vertexbuffer_flush
This variable is currently somewhat pointless, I was originally going to
use it to tell the graphics subsystem to completely rebuild the internal

functionality.

jp9000 cec11d624a OpenGL: Don't call glGetAttribLocation on outputs
Previously we were using glGetAttribLocation on all inputs/outputs and
then just discarding if it was returned -1.  However, we have a boolean
value of 'input' in gl_parser_attrib, so there's no need to be doing
this and discarding potentially useful error handling information.

jp9000 efaafd7cb4 OpenGL: Fix erroneous handling of BGRX
BGRX was being treated as "BGR input" with "RGBA storage", where it
should have been "BGRA input" with "RGB storage".  So the input for the
texture was expecting 24 bits of packed BGR rather than 32bit BGRX
pixels, and was internally storing it with alpha available.

jp9000 0bec267e40 OpenGL: Fix swizzle code again for alpha textures
My prior code was incorrect;  I mixed up the two parameters, the
GL_TEXTURE_SWIZZLE_* parameter specifies the target channel, and the
value itself specifies the source channel.,  If that makes sense.

jp9000 51d338430f Only do the alpha swizzle on alpha textures
Avoids problems if swizzles are used elsewhere (like in the newer X11
plugins)

jp9000 bc33b09ba9 Revert OpenGL swizzle change
Was wrong to use the swizzle -- it was an incorrect assumption on my
part that this could work in the first place (despite working on
windows)

jp9000 362e008b87 OpenGL: Use texture swizzle for BGRA/BGR/A8
On some operating systems, with specific drivers it seems that BGR/BGRA
isn't properly treated as such in certain cases.  This fix will
hopefully force the formats to be treated as BGR/BGRA when actually
rendering, which should get around the implementation-specific issue.
