media-libs/osl: New package

A small but rich language for programmable shading in advanced
renderers and other applications, ideal for describing materials,
lights, displacement, and pattern generation.

New dependency for media-gfx/blender.
Closes: https://github.com/gentoo/gentoo/pull/6609

+From cb34603cce0a8814dc66f76ecc5ceeb04a8d3791 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] OpenShadingLanguage/RB-1.8: Change to GNUInstallDirs for
+ install paths
+
+The variables: BIN_INSTALL_DIR, LIB_INSTALL_DIR, INCLUDE_INSTALL_DIR,
+DOC_INSTALL_DIR, and MAN_INSTALL_DIR are defined but never used.
+Instead, hard coded paths to lib, include, and bin were used. This
+will cause difficulty on multi-lib systems or in cases where they
+are named differently. The existing variables were replaced by the
+GNUInstallDirs variables, which is compatible on all systems.
+
+The macro install_targets was defined, but never used in code,
+so all library installs were changed to use it.
+Thus all library installs now use GNUInstallDirs.
+
+INSTALL_DOCS variable is defined, so it's now controlling if
+the documentation is being installed.
+
