The largest new feature is that it is now possible to include other
files into the RML by using the "include" tag. This is useful for making
markup files more modular.
Also added some more options for existing things (e.g. built-in detail
options).
The previous method of rendering nebula fog didn't work correctly with
deferred shading since it changed the color of the material which
obviously caused some issues when it received light from a beam or a
weapon. This wasn't very noticable before because the directional lights
were handled correctly but since all the lighting operations have been
moved into the deferred shading phase it is very obvious that something
is wrong with our nebula rendering.
This fixes that by introducing a new shader which does a fullscreen pass
after resolving all the lights. It applies the usual fog formula based
on the depth of the fragment but it can only use a fixed distance range.
FSO support specifying a range for every object type but the default
range I chose should work properly for all ship types.
The new code only applies to opaque meshes. Transparent meshes are
fogged using the standard formula.
Specifying the fog rendering options is now handled by the materials
system and the implementation of gr_set_fog was pretty much empty so I
removed it.
There is nothing specific to OpenGL in that code anymore since it's all
handled in the shaders at this point. This will make the lighting
information available in the normal graphics code which allows to use
those values when filling the uniform buffer for the model rendering.
The HDR changes made the nebula bitmaps a lot less visible. This fixes
that by boosting the color of the bitmaps when they are rendered.
I choose 3 since that gives a similar look to 3.7.4 but that can be
further tweaked if desired.
I also added two debug scopes to help track down where that stuff was
actually rendered.
This fixes#712.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
includes:
full-colour & hud-colour headanis
cbanims & intelanims
mainhall animations (including playing in reverse)
Notably does not support ship/weapon select anims as they need
keyframes and there isn't anywhere to specify them in the apng format
