We never use the ::Angle unit internally, we just access the value. This
CL changes the default value to an Integer and drops the measurement.

This reverts commit 7829b7048d5cf13a4f1a806fed57f2440d1b5dec.
Reason for revert: Breaking the waterfall build. Looks like it's finding a leak it wasn't before?

Control Flow Integrity [1] indirect call checking verifies that function
pointers only call valid functions with a matching type signature. This
condition can be too strict, a common form of 'abstraction' relies on
function pointers being cast to generalize argument pointer types to
void*.
In LCMS these failures occur because of casts of function pointers called
as both _cmsInterpFn16 (cmsInterpFunction.Lerp16) and _cmsOPTeval16Fn (as
an argument to _cmsPipelineSetOptimizationParameters) types making it
difficult to refactor out easily. Instead, enabling the type
generalization build config weakens the type checking performed for
CFI-icall to accomodate this common type of casts.

Most of the API methods FPDFText operate on indices in terms of the
underlying stream of characters. This stream includes non-printing
control characters, which are not part of the visible text. The
majority of files do not appear to have these hidden characters so
there is a 1:1 correspondence between them. When they are present
conversion needs to occur to make sure that GetText doesn't attempt to
retrieve for a span that is out of range.
