301/*
302 We implement standard-looking 3D borders which have the following appearance:
303
304 The raised border:
305
306 WWWWWWWWWWWWWWWWWWWWWWB
307 WHHHHHHHHHHHHHHHHHHHHGB
308 WH GB W = white (HILIGHT)
309 WH GB H = light grey (LIGHT)
310 WH GB G = dark grey (SHADOI)
311 WH GB B = black (DKSHADOI)
312 WH GB
313 WH GB
314 WGGGGGGGGGGGGGGGGGGGGGB
315 BBBBBBBBBBBBBBBBBBBBBBB
316
317 The sunken border looks like this:
318
319 GGGGGGGGGGGGGGGGGGGGGGW
320 GBBBBBBBBBBBBBBBBBBBBHW
321 GB HW
322 GB HW
323 GB HW
324 GB HW
325 GB HW
326 GB HW
327 GHHHHHHHHHHHHHHHHHHHHHW
328 WWWWWWWWWWWWWWWWWWWWWWW
329
330 The static border (used for the controls which don't get focus) is like
331 this:
332
333 GGGGGGGGGGGGGGGGGGGGGGW
334 G W
335 G W
336 G W
337 G W
338 G W
339 G W
340 G W
341 WWWWWWWWWWWWWWWWWWWWWWW
342
343 The most complicated is the double border which is a combination of special
344 "anti-sunken" border and an extra border inside it:
345
346 HHHHHHHHHHHHHHHHHHHHHHB
347 HWWWWWWWWWWWWWWWWWWWWGB
348 HWHHHHHHHHHHHHHHHHHHHGB
349 HWH HGB
350 HWH HGB
351 HWH HGB
352 HWH HGB
353 HWHHHHHHHHHHHHHHHHHHHGB
354 HGGGGGGGGGGGGGGGGGGGGGB
355 BBBBBBBBBBBBBBBBBBBBBBB
356
357 And the simple border is, well, simple:
358
359 BBBBBBBBBBBBBBBBBBBBBBB
360 B B
361 B B
362 B B
363 B B
364 B B
365 B B
366 B B
367 B B
368 BBBBBBBBBBBBBBBBBBBBBBB
