Compiles and adds a shader to this program.
After adding all your shaders, remember to call link() to link them into a usable program.
If your app is built in debug mode, this method will assert if the program fails to compile correctly.
The shaderType parameter could be GL_VERTEX_SHADER, GL_FRAGMENT_SHADER, etc.
- Returns
- true if the shader compiled successfully. If not, you can call getLastError() to find out what happened.
