Classes
class	BindAttribute
	A BindAttribute inherits from PreLinkAction, it's purpose is to bind named attributes to named locations, i.e. it calls glBindAttributeLocation(). More...
class	BindFragDataLocation
	A BindFragDataLocation inherits from PreLinkAction, its purpose is to bind a fragment shader out to a named location and index. Using a BindFragDataLocation requires: More...
class	ContextProperties
	A ContextProperties provides an interface to query GL/GLES version and extensions. More...
class	PainterEngineGL
	A PainterEngineGL implements PainterEngine using the GL (or GLES) API. The PainterShaderRegistrar object returned by painter_shader_registrar() derives from glsl::PainterShaderRegistrarGLSL. In addition, when adding custom shaders, the shader types need to be derived from the shader types of the GLSL module, i.e. More...
class	PainterSurfaceGL
class	PreLinkAction
	A PreLinkAction is an action to apply to a Program after attaching shaders but before linking. More...
class	PreLinkActionArray
	A PreLinkActionArray is a conveniance class wrapper over an array of PreLinkAction handles. More...
class	Program
	Class for creating and using GLSL programs. More...
class	ProgramInitializer
	A ProgramInitializer is a functor object called the first time a Program is bound (i.e. the first time Program::use_program() is called). It's main purpose is to facilitate initializing uniform values. More...
class	ProgramInitializerArray
	Conveniance class to hold an array of handles of ProgramInitializer objects. More...
class	ProgramSeparable
	A ProgramSeparable inherits from PreLinkAction, its purpose is to set a GLSL program as separable, so that it can be used by a GLSL pipeline. Using a ProgramSeparable requires: More...
class	SamplerInitializer
	Class to intialize the binding points of samplers. If the uniform is an array, the first element will be given the specified binding point and successive elements in the array will be given successive binding points. More...
class	Shader
	Simple Shader utility class providing a simple interface to build GL shader objects using a glsl::ShaderSouce as its source code. More...
class	ShaderStorageBlockInitializer
	A ShaderStorageBlockInitializer is used to initalize the binding point used by a shader storage block (see the GL spec on glShaderStorageBlockBinding). Initializer is not supported in OpenGL ES. More...
class	TextureImage
class	TransformFeedbackVarying
	A TransformFeedbackVarying encapsulates a call to glTransformFeedbackVarying. Note that if there are multiple TransformFeedbackVarying objects on a single PreLinkActionArray, then only the last one added has effect. More...
class	UniformBlockInitializer
	A UniformBlockInitializer is used to initalize the binding point used by a bindable uniform (aka Uniform buffer object, see the GL spec on glGetUniformBlockIndex and glUniformBlockBinding. More...
class	UniformInitalizerBase
	A UniformInitalizerBase is a base class for initializing a uniform, the actual GL call to set the uniform value is to be implemented by a derived class in init_uniform(). More...
class	UniformInitializer
	Initialize a uniform via the templated overloaded function fastuidraw::gl::Uniform(). More...
class	UniformInitializer< c_array< const T > >
	Specialization for type c_array<const T> for UniformInitializer so that data behind the c_array is copied. More...
