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.
