Prior to this commit the returned values were always normalised to the
value returned by getHeightInPoints().
I.e. getAscentInPoints() + getDescentInPoints() would always equal
getHeightInPoints(), even if ascent or descent overrides were in place.
With this change in place getAscentInPoints() + getDescentInPoints()
will always equal
getHeightInPoints() * (getAscentOverride() + getDescentOverride())
JUCE classes don't use this value for layout logic, so this commit
causes no visible changes in how JUCE draws text.
This commit removes the various compiler-specific JUCE_DEPRECATED macros and replaces them with C++14's deprecated attribute. It also removes the JUCE_CATCH_DEPRECATED_CODE_MISUSE flag as we can rely on the override specifier catching usage of these old virtual methods, and tidies up the DOXYGEN preprocessor checks as they were inconsistent across the codebase.
Previously, it wasn't safe to access Font instances from multiple
threads because there was a chance that they might reference the same
shared internal state. In this case, calling getTypeface() or getAscent from
two threads simultaneously would cause a race on the typeface and ascent
data members, even though the Font instances appeared to be disjoint.
With this change in place, it is now safe to use Font instances from
multiple threads simultaneously.
It is still an error to modify the same Font instance from multiple
threads without synchronization!
// Fine:
Font a;
Font b = a;
auto futureA = std::async (std::launch::async, [&a] { /* do something with a */ });
auto futureB = std::async (std::launch::async, [&b] { /* do something with b */ });
// Bad idea:
Font f;
auto futureA = std::async (std::launch::async, [&f] { /* do something with f */ });
auto futureB = std::async (std::launch::async, [&f] { /* do something with f */ });
