CoglFuncPtr ()

void                (*CoglFuncPtr)                      (void);

The type used by cogl for function pointers, note that this type is used as a generic catch-all cast for function pointers and the actual arguments and return type may be different.

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 COGL_PIXEL_FORMAT_RGB_888 would have the red component in the lowest address, green in the next address and blue after that regardless of the endinanness of the system.

For the 16-bit formats the component order specifies the order within a 16-bit number from most significant bit to least significant. So for COGL_PIXEL_FORMAT_RGB_565, the red component would be in bits 11-15, the green component would be in 6-11 and the blue component would be in 1-5. Therefore the order in memory depends on the endianness of the system.

When uploading a texture COGL_PIXEL_FORMAT_ANY can be used as the internal format. Cogl will try to pick the best format to use internally and convert the texture data if necessary.
