* Remove hardcoded default font name.
This means the `fonts/fonts.ini` file is now mandatory
and must contain definition of all 9 font types.
Old mods relying on an incomplete `fonts.ini` file might break.
A separate PR creating the required `fonts/fonts.ini` file
should be merged before this pull request.
* Simplify `CFontLoader`.
* Return `std::optional` instead of returning a default.
* Remove the now unnecessary `std::map`s.
* Remove the now unnecessary `GetFontType` method.
* Improve Gfx::FontType.
* Provide `ToString` function for the enum, which is now
used for logs and by `CFontLoader`.
* Provide `ToBoldFontType` and `ToItalicFontType` functions.
* Replace hex literals with binary literals for readability.
* Move font caching related code to a new private class `FontsCache`.
* Add neccessary changes because of changes made in `CFontLoader`.
* Add minor code improvements like renames and formatting.
* Split the code into smaller functions for readability.
* Simplify the `CText` class.
* Apply the rule of 5 to the `CachedFont` structure.
* Engine will now use it to render terrain
* Added directional light source
* Added dynamic shadows
* Moved visibility computation to CEngine
* Removed uniform buffers
Fix mistakes after previous merge and make it compile.
Rewrite the function interpolating between time stamps as it was
written after the original pull request was created. Add unit tests
for it.
I couldn't help myself and also changed some enums to enum classes and
did some renames.
The issue is that the \button fragments in SatCom are replaced with
invalid UTF-8 bytes, hence those bytes need to be handled as a special
case when checking for UTF-8 character length.
When the text is processed e.g. in `Gfx::CText::Justify`, there are
generally two arrays: `text` and `format`. The second one is interpreted
as a font for a given character, e.g. `text[i]` has font `format[i]`.
Now, in the loops the index for `text` is increased by the length of
the character, e.g. 1 to 4 bytes, whereas index for `format` is
only incremented. It seems there's an assumption that `format` treats
multibyte characters as one byte, which doesn't seem to be true by
looking at the process of filling up the `format` array. This can result
in using wrong font e.g. FONT_SATCOM for the \button character which
should be FONT_BUTTON, hence the `StrUtils::Utf8CharSizeAt` method
complains about unexpected continuation byte via exception, causing
the crash.
Incrementing the index by the UTF-8 length seems to have fixed the
issue. However, I am not sure if I haven't broken anything else by this
and if I analyzed the intended behaviour correctly.
Gfx::CText needs a major refactor IMHO.

Jeff's patch was written for the 0.1.12 stable release.
Adapted to work with the "dev" branch (as of commit 13098ee).
Moved list of mods logic to a new CModManager class.
The list of enabled mods is now managed by a flag instead of directory
names of mods.
Mods are now disabled by default.
Also general cleanup, fixing issues from the code review in
https://github.com/colobot/colobot/pull/1191 and fixing linter issues.
Regression: the state of enabled/disabled mods is now not persistent.
The plan is to use some kind of config file for this.
F12 is used by Visual Studio debugger to trigger a breakpoint and apparently it cannot be changed:
"The F12 key is reserved for use by the debugger at all times, so it should not be registered as a hot key. Even when you are not debugging an application, F12 is reserved in case a kernel-mode debugger or a just-in-time debugger is resident."

When rendering the shadow map offscreen using framebuffer objects, it's
not necessary to create a color renderbuffer. Currently
FramebufferParams only lets you choose between a renderbuffer and a
texture for both color and depth attachments. This changes that, and now
you can ask for a texture, a renderbuffer, or nothing.
This improves performance. On my computer, with an 8192x8192 shadow map,
this improves overall frame time by 8.0%.
Shadow shimmering is a visual artefact where the outlines of shadow
mapped objects don't stay stable when the camera is moved or rotated.
The reason is that as the shadow map's origin moves, the objects
rendered to the shadow map have temporal aliasing around their edges.
The solution is to only move the shadow map in texel-sized increments.
Because the shadow map's projection is orthographic, moving the shadow
map origin in texel increments ensures that objects that aren't moving
don't show any temporal aliasing, as the position of the samples of the
object in worldspace stay the same.
This significantly speeds up text rendering. On my computer, looking at
the program editor with a full screen of text, this commit takes the
framerate from under 30 to 60 (hitting vsync).
Performance could be further improved in the gl33 renderer by using
instancing or glPrimitiveRestartIndex instead of glMultiDrawArrays, but
that would be a more invasive change.
All of the interface rendering could use a unified quad batching system,
instead of it being limited to CText, but that would require some
refactoring in CText as it currently draws using a different coordinate
space to the rest of the interface.
Fixes#1104.
Currently the engine can draw debug spheres to show crash sphere
positions. This extends this to draw arbitrary spheres and cuboids,
transformed arbitrarily. With these in place it's now very quick and
easy to create a debug visualisation - for example, it's a one-line code
change to render the bounding box or sphere of every EngineObject.
This commit improves rendering performance by doing a better job of
checking whether an object is visible via its bounding sphere or not.
The engine maintains a bounding box for each EngineBaseObject that's
exactly large enough to fit every vertex. From this, it computes a
bounding sphere, and only draws objects if the sphere is within the view
frustum. Previously, the bounding sphere was always centered on the
EngineBaseObject's origin, even for models where the bounding box center
is significantly offset from the origin. Now, the bounding sphere is
always the tightest sphere which fits the bounding box.
-Wmissing-declarations enforces that every function (except for static
functions) must be declared separately before it's defined. This
essentially enforces that every function must be either static, or
declared in a header elsewhere.
This helps the optimizer, as it can do a better job of inlining if it
knows that a function won't be used outside of a given file. It also
helps -Wunused-function (which is enabled by -Wall) find more unused
functions.
Note that Clang spells this option -Wmissing-prototypes, which
confusingly is the name of a related but different warning option under
GCC.
SystemTimeStamp used to be an opaque class, as it was provided by
`system_{linux/other/windows}.h`. Because of this, code dealt in
SystemTimeStamp pointers, and getting the current timestamp required a
memory allocation. Now SystemTimeStamp is just a
`std::chrono::time_point`, we can make the code cleaner and faster by
just directly keeping SystemTimeStamp instead of pointers around.
