A common requirement is the fast upload of pixel data. In order to allocate the most appropriate image buffer, we need knowledge of the destination. The most obvious example is that we could use a shared-memory region for the image to avoid the transfer cost of uploading the pixels to the X server. Similarly, gl, win32, quartz... The other side of the equation is that for manual modification of a remote surface, it would be more efficient if we can create a similar image to reduce the transfer costs. This strategy is already followed for the destination fallbacks and this merely exposes the same capability for the application fallbacks. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> |

Cairo Utilities =============== There are a varieties of utilities we use with cairo. backtrace-symbols ----------------- This is a small shared library designed to be preloaded by the linker and its purpose is to make the backtrace_symbols() function of glibc produce more useful source reference information. Build by: make backtrace-symbols.so and use by: LD_PRELOAD=$PWD/backtrace-symbols.so app-to-run This code should be contributed back to glibc at some point. malloc-stats ------------ This is a small shared library designed to be preloaded by the linker and its purpose is to make the malloc_stats() function of glibc produce more useful information. Build by: make malloc-stats.so and use by: LD_PRELOAD=$PWD/malloc-stats.so app-to-run This works best when backtrace-symbols is in use. That is: LD_PRELOAD="$PWD/backtrace-symbols.so $PWD/malloc-stats.so" app-to-run cairo-trace ----------- This tool can be used to trace all the cairo function calls made by an applications. This is useful for either extracting a test case triggering a bug from an application, or simply to get a general idea of how an application is using cairo. cairo-api-update and xr2cairo ----------------------------- These two scripts were used to convert source code written for pre-1.0 cairo to newer API. See $(top_srcdir)/PORTING_GUIDE for more information. These files are obsolete now and may be removed in a future version. cairo-view and waterfall ------------------------ These are two pycairo scripts useful for testing the toy font backend.
