- PushFont(font, 20.0f) // Change font and set size to 20.0f

- PushFont(font, font->LegacySize) // Change font and set size to size passed to AddFontXXX() function. Same as pre-1.92 behavor, for fixed size fonts.
- To use old behavior:
- use 'ImGui::PushFont(font, font->LegacySize)' at call site (preferred).
- or set 'ImFontConfig::Flags |= ImFontFlags_DefaultToLegacySize' in AddFont() call
(not desirable as it requires e.g. all third-party code to be aware of it).
- To use old behavior use 'ImGui::PushFont(font, font->LegacySize)' at call site.
We intentionally didn't add a default parameter because it would make the long-term
transition more difficult.
- Kept inline redirection font. Will obsolete.

- Fonts: added ImFontFlags (currently needs to be passed through ImFontConfig until
we revamp font loading API):
- ImFontFlags_DefaultToLegacySize: for legacy compatibility: make PushFont() calls
without explicit size use font->LegacySize instead of current font size.
- ImFontFlags_NoLoadError: disable erroring/assert when calling AddFontXXX()
with missing file/data. Calling code is expected to check AddFontXXX() return value.
- ImFontFlags_NoLoadGlyphs: disable loading new glyphs.

- PushFont() API now has a REQUIRED size parameter.
- Before 1.92: PushFont() always used font "default" size specified in AddFont() call. It is equivalent to calling PushFont(font, font->LegacySize).
- Since 1.92: PushFont(font, 0.0f) preserve the current font size which is a shared value.
- To use old behavior: (A) use 'ImGui::PushFont(font, font->LegacySize)' at call site (preferred). (B) Set 'ImFontConfig::Flags |= ImFontFlags_DefaultToLegacySize' in AddFont() call (not desirable as it requires e.g. third-party code to be aware of it).
- To use old behavior: use 'ImGui::PushFont(font, font->LegacySize)' at call site.
- Kept inline single parameter function. Will obsolete.
- Fonts: **IMPORTANT** on Font Merging:
- When searching for a glyph in multiple merged fonts: font inputs are now scanned in orderfor the first font input which the desired glyph. This is technically a different behavior than before!
