Combine identical SetBoxShadow and SetTextShadow functions into one Drop shadow property Drop shadow menu UI test Initial rendering support for drop-shadow https://files.facepunch.com/alexguthrie/1b0511b1/devenv_wIlk5l0DF3.mp4 Multiple tests for mask, multiple filter modes, etc. https://files.facepunch.com/alexguthrie/1b0511b1/sbox-dev_quSj9lxmDS.png Shader cleanup + optimized compile Render each shadow separately, means we can have multiple drop shadows if we want Move drop-shadow stuff into its own shader, makes sense to separate this out now Minor tweaks + optimized compile for ui_filter and ui_dropshadow Clean up layer rendering Remove ExCSS import (???) Recompile ui_filter.shader
