9150c23c04 imgui_freetype: fixed a packing issue which in some occurrences would prevent large amount of glyphs from being packed correctly. (#5788, #5829) 
This seemingly innocuous change sursingly had very large side-effects of completly breaking packing for the test font mentioned in above issue. Not even sure why tbh. New code matches what stb_truetype's stbtt_PackBegin() does.

Silence memset warning. (#3505) 
Compiling the code as-is results in the following warning:

-->8--
imgui_freetype.cpp:341:72: warning: ‘void* memset(void*, int, size_t)’
        clearing an object of type ‘struct ImFontBuildSrcDataFT’ with no
        trivial copy-assignment; use assignment or value-initialization
        instead [-Wclass-memaccess]
  341 |     memset(src_tmp_array.Data, 0, (size_t)src_tmp_array.size_in_bytes());
      |                                                                        ^
imgui_freetype.cpp:302:8: note: ‘struct ImFontBuildSrcDataFT’ declared here
  302 | struct ImFontBuildSrcDataFT
      |        ^~~~~~~~~~~~~~~~~~~~
--8<--

This is caused by presence of ImVector<> directly in ImFontBuildSrcDataFT data
structure, as well as in the child ImBitVector. Since ImVector<> has a
constructor, the compiler infers that initialization by memset is not valid.
Such initialization is not a bug, however, as the default ImVector<> ctor just
sets the structure data members to 0, which is exactly what the memset does.

Casting the data structure address to void* pointer silences this warning.

714fe29d1a Replace manual flooring with IM_FLOOR() macro. (#2850) 
Macro is used to ensure that flooring operation is always inlined even in debug builds. __forceinline does not force inlining in /Od builds with MSVC.
