Updated to latest recommended build settings, increased deployment target to 10.7 Further tweaks to Xcode project Now works as well as possible in Xcode 11 Figured out method of referencing GLSL generated C files outside of code directory Update README.md Add C syntax highlighting to readme Simplify glsl -> C stringification Make LCC path resolution more robust GitHub Actions setup Remove old CI system configurations Add status badge to README Fix shader stringify Run apt-get update before installing deps Avoid platform sed differences Run actions on pull request too Use `r_texturemode GL_LINEAR_MIPMAP_LINEAR` by default [sdl] Turn tentative definition into actual definition. Add TOOLS_CFLAGS to build preamble Fix use of TOOLS_CC being reported as CC Use the correct compiler for tools when cross building under cygwin Allow using pulseaudio for SDL audio capture Restore bots crushing unseen player on q3tourney6 in non-CTF Fix the number of weights in the IQM model calculation Fixes a crash when compiling the project on windows in 64 bit mode.
