If a LogicToLogic uses fixed units, we can use o3tl::convert instead. We can also do the same for all other cases where LogicToLogic is used, but that needs additional investigation to determine if it is safe to do so. Note: MapUnit::Pixel is converted to o3tl::Length::pt because it assumed 72 PPI for a logical pixel, which corresponds with the conversion rate of a point (72 PPI). Today, 96 PPI is standard, which is also used for o3tl::Length:px.

LibreOffice Template Library
Very basic template functionality, a bit like boost or STL, but specific to LibreOffice.
o3tl stands for "OOo [o3, get it?] template library", in which OOo stands for OpenOffice.org, predecessor of LibreOffice.
From https://blog.thebehrens.net/2006/01/15/update-cow_wrapper-is-available-now/ The scope for o3tl is admittedly kind of ambitious, as it should contain "...very basic (template) functionality, comparable to what's provided by boost or stl, but specific to OOo (what comes to mind are e.g. STL adapters for our own data types and UNO, and stuff that could in principle be upstreamed to boost, but isn't as of now)."
Class Overview
-
[git:include/o3tl/cow_wrapper.hxx]A copy-on-write wrapper.
-
[git:include/o3tl/lazy_update.hxx]This template collects data in input type, and updates the output type with the given update functor, but only if the output is requested. Useful if updating is expensive, or input changes frequently, but output is only comparatively seldom used.
-
[git:include/o3tl/vector_pool.hxx]Simple vector-based memory pool allocator.
-
[git:include/o3tl/functional.hxx]Some more templates, leftovers in spirit of STLport's old functional header that are not part of the C++ standard (STLport has been replaced by direct use of the C++ STL in LibreOffice).
