PHP5 Modules Used By WordPress

Hi,

it would be great if there will be official page on codex describes what php5 modules are used by wordpress and for what they are used. For example we need php5-gd and php5-imagick to get resize image to work, but i can’t find info about this on official wordpress resources. I found this:

https://wordpress.stackexchange.com/questions/42098/what-are-php-extensions-and-libraries-wp-needs-and-or-uses/42212#42212

but it’s little bit outdated. Where can I post request about this? On trac there is no “component” related to documentation.
