324 * We sort the colormap by closeness and try to allocate the color
325 * closest to the target. If the allocation of this close color fails,
326 * which almost never happens, then one of two scenarios is possible.
327 * Either the colormap must have changed (since the last close color
328 * allocation or possibly while we were sorting the colormap), or the
329 * color is allocated as Read/Write by some other client. (Note: X
330 * _should_ allow clients to check if a particular color is Read/Write,
331 * but it doesn't! :-( ). We cannot determine which of these scenarios
332 * occurred, so we try the next closest color, and so on, until no more
333 * colors are within closeness of the target. If we knew that the
334 * colormap had changed, we could skip this sequence.
335 *
336 * If _none_ of the colors within closeness of the target can be allocated,
337 * then we can finally be pretty sure that the colormap has actually
338 * changed. In this case we try to allocate the original color (again),
339 * then try the closecolor stuff (again)...
340 *
341 * In theory it would be possible for an infinite loop to occur if another
342 * process kept changing the colormap every time we sorted it, so we set
343 * a maximum on the number of iterations. After this many tries, we use
344 * XGrabServer() to ensure that the colormap remains unchanged.
345 *
346 * This approach gives particularly bad worst case performance - as many as
347 * <MaximumIterations> colormap reads and sorts may be needed, and as
348 * many as <MaximumIterations> * <ColormapSize> attempted allocations
349 * may fail. On an 8-bit system, this means as many as 3 colormap reads,
350 * 3 sorts and 768 failed allocations per execution of this code!
351 * Luckily, my experiments show that in general use in a typical 8-bit
352 * color environment only about 1 in every 10000 allocations fails to
353 * succeed in the fastest possible time. So virtually every time what
354 * actually happens is a single sort followed by a successful allocate.
355 * The very first allocation also costs a colormap read, but no further
356 * reads are usually necessary.
