+[0:01][Recap and set the stage for the day, assuming that our certificates are not about to expire][:speech]
+[2:34][Recall Windows' rule for antialiasing fonts (up to 353px high), and set up to parse and update :font metadata][:speech]
+[4:33][Address the "hhfont creates corrupt PNG for "space" glyph" issue[ref

+[7:39][Check out test.hht with the determination to augment it with richer :font metadata][:"file format" :parsing :research]
+[9:18][Determine to break up ParseTopLevelBlock() into bundles of uniform operations, and permit such things as calling UpdateAssetMetadata() for many individual glyphs][:parsing :research]
+[12:07][Introduce HandleCommonFields() for ParseTopLevelBlock() to call for many block types][:parsing]
+[16:05][Extract the "default" block :parsing out of ParseTopLevelBlock() for its caller ParseHHT() to perform, introducing ParseDefaultBlock()]
+[24:05][Extract the "font" block :parsing out of ParseTopLevelBlock(), introducing ParseFontBlock() and RequireIdentifier()]
+[28:45][Introduce RequireField() to compress out the field :parsing code]
+[30:07][Continue to implement ParseFontBlock() calling RequireField() and setting the Font header][:parsing]
+[34:24][Enable ParseFontBlock() to handle the Glyph and HorizontalAdvance arrays][:parsing]
+[40:19][Consult @Molly][:speech]
+[44:38][Continue to enable ParseFontBlock() to handle Glyph metadata, introducing ImportGlyph()][:parsing]
+[51:40][Enable ParseFontBlock() to handle the HorizontalAdvance metadata for every Glyph][:parsing]
+[54:16][Enable ParseFontBlock() to handle the rest of the Glyph metadata, including code point and alignment points][:parsing]
+[1:03:47][Introduce UpdateSingleAssetMetadata() for ParseFontBlock() to call][:"asset system" :parsing]
+[1:12:20][Change UpdateSingleAssetMetadata() to take an asset_file rather than asset_source_file, and additionally take an Errors stream and FileBaseName, for ParseFontBlock() to pass][:"asset system" :parsing]
+[1:17:52][Consider how to import glyphs specially, since they lack an asset index][:"asset system" :speech]
+[1:21:47][Introduce a synthetic asset file in ParseFontBlock() to denote our font assets][:"asset system" :parsing]
+[1:29:26][Set up ParseFontBlock() to rebuild differing glyph arrays, introducing BlockDiffers()][:parsing]
+[1:44:19][Implement BlockDiffers()]
+[1:48:50][Fix compile errors]
+[1:53:52][Stub out ImportGlyph() and a version of GetOrCreateAssetSourceFile() that takes the BaseName as a string][:parsing]
