Availabile	2.0 – present
Class Prefix	CA

QuartzCore, also known as Core Animation, is an Objective-C framework that creates simple animations on UI elements.

Debugging

Available in	2.0 –
Signature	`unsigned CAGetDebugFlags();`

Available in	2.0 –
Signature	`void CASetDebugFlags(unsigned flags);`

Applications linked with QuartzCore will recognize the following debugging (boolean) environment variables:

Flag	Environment variable
1	CA_COLOR_FLUSH^[1]
2	CA_COLOR_COPY
4	CA_COLOR_OPAQUE^[1]^[2]
8	CA_COLOR_NO_WAIT^[1]
16	CA_AUTO_FLUSH
32	CA_PRINT_TREE^[1]
64	CA_PRINT_OBJECTS
128	CA_LOG_IMPLICIT_TRANSACTIONS
256	CA_LOG_MEMORY_USAGE
512	CA_LOG_IMAGE_COPIES
1024	CA_PRINT_PERF
2048	CA_DISABLE_OCCLUSION_CULLING
4096	CA_DISABLE_DIRTY_REGIONS
8192	CA_LOG_TRIPLE_BUFFERING
16384	CA_COLOR_SUBPIXEL
32768	CA_DISABLE_RENDER
65536	CA_ALWAYS_RENDER
131072	CA_COLOR_OFFSCREEN
262144	CA_COLOR_DETACHED

Alternatively, you can use the CASetDebugFlags() to update the flags in runtime.
