Although normalized vectors in FSO are supposed to stay normalized, occasionally small floating point errors can pop up. In most cases these do not cause a problem, but in certain cases these errors can rapidly accumulate and corrupt an otherwise well-behaved matrix. This can most easily be seen with daisy-chained dock sequences or docked ships with angled dockpoints.
This PR audits the usage of `vm_vector_2_matrix_norm` to re-normalize vectors in cases where floating point errors could accumulate. There are also a few new Assertions for extra vigilance.
Follow-up to #6596. Fixes#6634.
Most places in the code that use `vm_vector_2_matrix` do so on already-normalized vectors. Changing these to `vm_vector_2_matrix_norm` avoids redundant normalization.
Original issue post #6509. This flag controls if set-camera-host sexp uses the model's eyepoint for the camera position and orientation when no submodel is specified.
Without the flag, the camera will use the model's origin position and orientation.
Make these convenient functions even more convenient:
1. Change `object_get_model()` to `object_get_model_num()` and `object_get_model_instance()` to `object_get_model_instance_num()` to more accurately reflect what they do
2. Add new `object_get_model()` and `object_get_model_instance()` functions to return `polymodel*` and `polymodel_instance*` values.
This refactors the object_h struct to store objects as indexes rather than pointers. This is a prerequisite for making the collection of objects dynamic in the future. See also #6100.
Follow-up to #5800 and #5829.

Use a simpler, more robust, and more correct method of sharing the fire direction among beams: replicate the actual beam vector for all firing points. This further cleans up and simplifies the beam firing code and also clarifies some vector math.
For subtitles drawn using the `$Show-subtitle base resolution:` feature, text near the side of the screen would get clipped off mysteriously. The clipping corresponded precisely to the edge of a 4:3 boundary, which led me to discover that the clip boundary was still at the side of a 4:3 box, rather than a 16:10 box as was expected. Explicitly setting the clip boundary when setting the screen scale fixed the issue.
For any graphics coders in the know, is this actually the proper fix?
When the `$Use host orientation for set-camera-facing` flag in game_settings.tbl is active, the camera will use the host's orientation as a basis for rotation. However if there is no host, the camera unintentionally inherited its old stale orientation. Instead the camera should base its new orientation on the identity matrix which is the expected behavior.
By specifying a base resolution in game_settings.tbl, subtitles can be scaled to the screen in the same way as HUD gauges. This can be used to prevent subtitles from appearing smaller at larger resolutions.
Depends on and is a follow-up to #4157.
What it says on the tin. This allows more precise positioning of subtitles, and a future PR will add the ability to scale them according to screen resolution.
Consolidated these functions and replaced the `find_submodel_point_*` functions with their closest `world_find_` counterparts. (One of those functions may not have actually worked correctly.) Also use the correct coordinate logic when returning normals from collision info in scripting.
Related to #3985 although not yet a fix for it.
As @Baezon figured out, when a host exists, `get_info` will return the orientation relative to the host. When there is no host, `get_info` returns the absolute orientation. In the latter case, `set_rotation_facing` does not need to do extra calculations to find the delta orientation.
Follow-up to #3989.
This is a system for storing arbitrary data in the config file and then
easily retrieving it later on. This has full Lua support for exposing
the available options in a custom UI and changing the values of the
options. This ported some of the existing command line options over to
the new system which is opt-in for the moment by using a mod_table flag.
This maintains the type information which can be used for enforce
const-correctness and also for implementing more advanced ways of
handling the type information.
All transformations are now handled by shaders so there is nothing
special going on in the graphics API specific code anymore. Since model
uniform buffers require access to these matrices I moved the matrix
handling out of the graphics API code.
This allows to use standard TrueType Fonts for text rendering in FSO. It uses the NanoVG library which provides the ability of drawing 2D shapes. This library is used for most 2D operations now and can also be used directly by using the PathRenderer class.
Replaces calls to double-precision floating point trig functions with
calls to single-precision floating point trig functions as follows:
cos() -> cosf()
sin() -> sinf()
tan() -> tanf()
acos() -> acosf()
asin() -> asinf()
atan() -> atanf()
This allows the compiler to avoid generating unnecessary instructions
that convert a float to a double and then a double back to a float.
