Enums

AttributeType	Data types for the components of a vertex attribute.
BitmapError	Error codes that can be thrown when performing bitmap operations. Note that gdk_pixbuf_new_from_file can also throw errors directly from the underlying image loading library. For example, if GdkPixbuf is used then errors GdkPixbufErrors will be used directly.
BlendStringError	Error enumeration for the blend strings parser
BufferError	Error enumeration for Buffer
BufferUpdateHint	The update hint on a buffer allows the user to give some detail on how often the buffer data is going to be updated.
DepthTestFunction	When using depth testing one of these functions is used to compare the depth of an incoming fragment against the depth value currently stored in the depth buffer. The function is changed using DepthState::set_test_function.
Driver	Identifiers for underlying hardware drivers that may be used by Cogl for rendering.
FeatureID	All the capabilities that can vary between different GPUs supported by Cogl. Applications that depend on any of these features should explicitly check for them using cogl_has_feature or cogl_has_features.
FilterReturn	Return values for the CoglXlibFilterFunc and CoglWin32FilterFunc functions.
FogMode	The fog mode determines the equation used to calculate the fogging blend factor while fogging is enabled. The simplest FogMode::Linear mode determines f as:
FrameEvent	Identifiers that are passed to CoglFrameCallback functions (registered using Onscreen::add_frame_callback) that mark the progression of a frame in some way which usually means that new information will have been accumulated in the frame’s corresponding FrameInfo object.
FramebufferError
GLES2ContextError	Error codes that relate to the cogl_gles2_context api.
IndicesType	You should aim to use the smallest data type that gives you enough range, since it reduces the size of your index array and can help reduce the demand on memory bandwidth.
MaterialAlphaFunc	Alpha testing happens before blending primitives with the framebuffer and gives an opportunity to discard fragments based on a comparison with the incoming alpha value and a reference alpha value. The MaterialAlphaFunc determines how the comparison is done.
MaterialFilter	Texture filtering is used whenever the current pixel maps either to more than one texture element (texel) or less than one. These filter enums correspond to different strategies used to come up with a pixel color, by possibly referring to multiple neighbouring texels and taking a weighted average or simply using the nearest texel.
MaterialLayerType	Available types of layers for a Material. This enumeration might be expanded in later versions.
MaterialWrapMode	The wrap mode specifies what happens when texture coordinates outside the range 0→1 are used. Note that if the filter mode is anything but MaterialFilter::Nearest then texels outside the range 0→1 might be used even when the coordinate is exactly 0 or 1 because OpenGL will try to sample neighbouring pixels. For example if you are trying to render the full texture then you may get artifacts around the edges when the pixels from the other side are merged in if the wrap mode is set to repeat.
PipelineAlphaFunc	Alpha testing happens before blending primitives with the framebuffer and gives an opportunity to discard fragments based on a comparison with the incoming alpha value and a reference alpha value. The PipelineAlphaFunc determines how the comparison is done.
PipelineCullFaceMode	Specifies which faces should be culled. This can be set on a pipeline using Pipeline::set_cull_face_mode.
PipelineFilter	Texture filtering is used whenever the current pixel maps either to more than one texture element (texel) or less than one. These filter enums correspond to different strategies used to come up with a pixel color, by possibly referring to multiple neighbouring texels and taking a weighted average or simply using the nearest texel.
PipelineWrapMode	The wrap mode specifies what happens when texture coordinates outside the range 0→1 are used. Note that if the filter mode is anything but PipelineFilter::Nearest then texels outside the range 0→1 might be used even when the coordinate is exactly 0 or 1 because OpenGL will try to sample neighbouring pixels. For example if you are trying to render the full texture then you may get artifacts around the edges when the pixels from the other side are merged in if the wrap mode is set to repeat.
PixelFormat	Pixel formats used by Cogl. For the formats with a byte per component, the order of the components specify the order in increasing memory addresses. So for example PixelFormat::Rgb888 would have the red component in the lowest address, green in the next address and blue after that regardless of the endianness of the system.
PollFDEvent	A bitmask of events that Cogl may need to wake on for a file descriptor. Note that these all have the same values as the corresponding defines for the poll function call on Unix so they may be directly passed to poll.
RendererError
ShaderType	Types of shaders
SnippetHook	SnippetHook is used to specify a location within a Pipeline where the code of the snippet should be used when it is attached to a pipeline.
StereoMode	Represents how draw should affect the two buffers of a stereo framebuffer. See Framebuffer::set_stereo_mode.
SubpixelOrder	Some output devices (such as LCD panels) display colors by making each pixel consist of smaller “subpixels” that each have a particular color. By using knowledge of the layout of this subpixel components, it is possible to create image content with higher resolution than the pixel grid.
SystemError	Error enumeration for Cogl
TextureComponents	See Texture::set_components.
TextureError	Error codes that can be thrown when allocating textures.
TexturePixmapX11Error	Error codes that can be thrown when performing texture-pixmap-x11 operations.
TexturePixmapX11ReportLevel
TextureType	Constants representing the underlying hardware texture type of a Texture.
VerticesMode	Different ways of interpreting vertices when drawing.
Winding	Enum used to represent the two directions of rotation. This can be used to set the front face for culling by calling Pipeline::set_front_face_winding.
WinsysFeature
WinsysID	Identifies specific window system backends that Cogl supports.
