- load glyph with FT_LOAD_IGNORE_TRANSFORM for bbox as final bbox is rotated at once later (fixes "double-rotation" per glyph for calculating bbox) - reload the rotated glyph for painting after that (only if angle != 0) - rotate the original bbox at 0,0 and do not throw away xMin/yMin (drawing-rotation is also based at "origin" point - including the bearingX, see http://www.freetype.org/freetype2/docs/glyphs/glyphs-3.html#section-3) - this fixes the "left-shift"-problem also when angle = 0 - removed "xb/yb" and use "x/y" directly for offsetting brect (no need for adding "x1/y1" and substracting "yd" later) - removed therefore unused "yd" helper var which seems tried to fix parts of the original problems - initialize x/y with 0 instead of -1 in php_imagettftext_common() to make image*text() and image*bbox() results identical (there was a -1px shift in image*bbox() before) - fixed gdroundupdown() for negative numbers (-256 / 64 gives -5 instead of -4 before) - rotate kerning-delta by given angle (fixes completely wrong kerning and therefore wrong bounding box if angle != 0) - changed 3 tests and added a new one to test for the new (better) coordinates
