Adds more log information for effects, such as the reformatted effect code, parameters, techniques and passes. This is useful for tracking down issues and what actually ends up being compiled in the end, without having to guess where the error is actually at, as what is compiled and what was originally there usually differ by a lot.
This information is only logged if libobs is compiled in debug and _DEBUG_SHADERS is defined and not compiled if either of those are not the case.
Add support for debug markers via D3DPERF API and KHR_debug. This makes
it easier to understand RenderDoc captures.
D3DPERF is preferred to ID3DUserDefinedAnnotation because it supports
colors. d3d9.lib is now linked in to support this.
This feature is disabled by default, and is controlled by
GS_USE_DEBUG_MARKERS.

Currently SrcBlendAlpha and DestBlendAlpha are both ONE, and can
combine together to form two. This is not a noticeable problem for
UNORM targets because the channels are clamped, but it will likely
become a problem if FLOAT targets are more widely used.
This change switches DestBlendAlpha to INVSRCALPHA, and starts
backgrounds as opaque black instead of transparent black. The blending
behavior of stacked transparents is preserved without overflowing the
alpha channel.
Adds api functions to extract gs_eparam_t values, including
gs_effect_get_val(), gs_effect_get_val_size(),
gs_effect_get_default_val() and gs_effect_get_default_val_size()
Gives the ability to retrieve param annotations. Blocks wrapped in <>
following a parameter.
For example:
float slider < float max_value = 10.0; float min_value = 0.0; >;
These blocks are not for shading purposes but to help describe the
shader's gui as in the example above.
Adds graphics api functions for retrieving annotations:
size_t gs_param_get_num_annotations(const gs_eparam_t *param);
gs_eparam_t *gs_param_get_annotation_by_idx(const gs_eparam_t *param,
size_t annotation);
gs_eparam_t *gs_param_get_annotation_by_name(const gs_eparam_t *param,
const char *name);
(Note: This commit also modifies libobs-d3d11 and libobs-opengl)
Allows the ability to flush data directly without having to use the
buffer's internal data.
Allows the caller to manage his/her own vertex/index buffer data if
desired, working around the design flaw of having to rely on a
vertex/index buffer's internal data.
Prevents from having to pass ownership of buffer data from caller when
using gs_vertexbuffer_create() or gs_indexbuffer_create() (which is a
design flaw).
Under certain circumstances it's necessary to seek, but if the frame
isn't loaded for the position that's being seeked to, it won't update
the texture. This just ensures the texture will update when seeking.
Passing 0,0 texture size should be considered legal, and safely return
false to indicate that rendering can't begin. Also there's no need to
try to use the current swap chain's width/height if either of the sizes
are 0, there's no need try try to "force" success here anymore.
Adds warnings for graphics functions to ensure that graphics functions
are called within an active graphics context, and add warnings if
required pointer parameters are null.
