This commit enhances text rendering by leveraging FreeType and a dynamic
font atlas. Previously, GUI scaling relied on bitmap fonts, which led to
blurry and distorted text when scaling up. Now, we scale the font size
directly using FreeType, resulting in much sharper and more readable
text at any GUI scale.
Key improvements:
- Replaced bitmap font scaling with true font size scaling via FreeType.
- Reduced glyph cache dependency on fixed positions, relying on shader
scaling instead.
- Switched to float-based glyph positioning for more accurate rendering
and scaling.
These changes ensure clean and consistent text appearance across
different GUI scales.
Replace premade bitmap fonts with FreeType2 and dynamic texture atlas.
Switched from static, premade bitmap fonts to runtime-generated glyphs using FreeType2.
Glyphs are rendered on demand into a dynamic texture atlas, improving scalability,
font quality, and support for internationalization.
Currently using RGBA format for compatibility across all render
paths while initial support for R8_UNORM is being added.
This prepares for future optimizations in VRAM and performance
Includes groundwork for gamma-corrected blending and future swizzling support.
Avoid cases of filenames
Update years in terms and other legal(ish) documents
Don't update years in license headers, since change is not meaningful
Will add linter rule in seperate commit
Happy recompiling everyone!

This makes incremental recompilation faster when changing static
interned strings.

GUIObjectBase is made a IGUIObject* to avoid including those headers
un-necessarily. Subsequent diffs ought to clean up the various of
pointers for that with a similar type with reference semantics.
Also:
- Add standard C and C++ headers (mostly cstring for memcpy, string and
vector) where needed.
- Swap out some includes for forward declarations
- Clean up un-necessary boost includes in precompiled and other headers.
- Clean up precompiled headers, including fewer things.
- Move ACPI to the windows-specific folder as it's included there only
and mostly specific to that platform.
Thanks Stan for the testing.

This fixes the problem where passing a non-ASCII string to
debug_printf(L"%hs", s) caused vswprintf_s to fail on Linux (because it
doesn't know what encoding the char* is meant to have). Now debug
messages will remain as UTF-8 until they reach the OS.
Fixes#3021.
This was SVN commit r16332.
sys_vswprintf relies on platform-specific printf implementations, which
vary widely between platforms (in handling of truncation, return values,
use of %s/%S/%hs/%ls for mixing char and wchar_t strings, etc) and are
therefore a pain.
Use cppformat's fmt::sprintf instead, which has very similar syntax to
sprintf but is more C++ish and is portable.
Also, wchar_t is stupid, so use char* strings (which are expected to be
UTF-8) in CLogger. This creates a bit of a pain with changing all
callers to convert to char* strings, but that's their fault for not
using UTF-8 already.
Refs #3011.
This was SVN commit r16182.
Add optional clipping rectangle to CTextRenderer. Strings that are
printed
outside the vertical extent of the clipping rectangle will be
immediately
skipped. This greatly reduces the cost of large scrollable text boxes.
This was SVN commit r14019.
When CTextRenderer is given multiple strings with no differences other
than position, render them in a single glDrawElements call to reduce
driver overhead.
Also avoid some unnecessary copies of std::wstrings.
This helps performance a bit with large GUI text boxes.
This was SVN commit r14018.
Replace unifont with CFont and CFontManager, since the h_mgr interface
was
needlessly inconvenient.
Load the font textures through CTextureManager, to support dynamic
reloading (e.g. when resetting GL state - see #741).
Add CFontMetrics as a convenient wrapper for code that just wants to
measure text.
Fixes#1117.
This was SVN commit r14016.
Switch all the constant strings in graphics code to use the new
variables.
This avoids the cost of instantiating CStrInterns at runtime every
frame.
This was SVN commit r13906.
