Tips

OpenGL glCreateShaderProgram may provide faster build per-

formance than a sequence of glCompilerShader and

glLinkProgram. However, it only creates a single shader stage

program.

Not all shader objects need a main() function. Multiple shader

objects can be linked together in the same program to allow shar-

ing the same code between different programs.

Build all GLSL shaders and programs first, and then query the

results to hide build and query latency.

Call glDeleteShader after attaching a shader to a program to

simplify cleanup later.
