Our converter PNG export module supports 3 built-in compression levels

• none
• default libpng compression

However, this functionality is currently unused as the converter is hardcoded to always use the default compression setting. We should implement a way to set the desired compression

Something that could help the documentation would be a glossary that certain terms could link to. A pointer would be a good candidate, or C data structures (struct/union) in general. Also extension type, terms like extern or inline, etc. It wouldn't have to replicate a complete specification o

Current compilervars is not exposed via conans.tools which means that only conanfiles that make use of the CMake and vcproj build helpers can reasonably use the Intel compiler. Please export compilervars and the _dict and _command variants in the conans.tools module.

Blocker for conan-io/conan-center-index#2499.
