Detailed Description

Wraps a GLSL program to which you can bind vertex, fragment and geometry shaders.

Uniforms

You have 5 ways to set the value of a uniform:

call useProgram() to activate the GLSLProgram and directly call glUniform* (see also getUniformLocation()).
add a Uniform to the GLSLProgram UniformSet, see vl::GLSLProgram::getUniformSet().
add a Uniform to the Actor's UniformSet, see vl::Actor::getUniformSet().
add a Uniform to the Actor's Shader UniformSet, see vl::Shader::getUniformSet().
directly update the uniform value from ActorEventCallback::onActorRenderStarted() using the standard glUniform*() OpenGL functions. In this case you have to make sure that all the Actors using a given GLSLProgram/Shader write such uniform.

Remarks:: A Uniform must be setup using one and only one of the 5 previously mentioned methods.

Attribute Location Bindings

In order to explicity specify which attribute index should be bound to which attribute name you can do one of the following.

call glBindAttribLocation() with the appropriate GLSLProgram::handle(). This is the most low level way of doing it.
call bindAttribLocation() as you would do normally with glBindAttribLocation() but with the difference the you don't need to specify the GLSL program handle.
create a list of attribute name/indices that will be automatically bound whenever the GLSLProgram is linked. In order to do so you can use the following functions setAutoAttribLocations(), autoAttribLocations(), clearAutoAttribLocations(), addAutoAttribLocation(), removeAutoAttribLocation().

Note that for option #1 and #2 you need to relink the GLSLProgram in order for the changes to take effect (linkProgram(force_relink=true)). Option #2 and #3 automatically schedule a re-link of the GLSL program. See also http://www.opengl.org/sdk/docs/man/xhtml/glBindAttribLocation.xml
