595cc19471 Fixes for doublebuffering. (Nearly?) correct implementation of -compositeGState: and -drawGState:. Temporarily fixed image drawing issues by lying about drawing to screen.

properly look up the glyph for a character.

7bc9e1a05a Fixed erroneous offset of glyphs by taking -defaultLineHeightForFont, multiplying by 0.66, and adding that to pt.y. No idea why 0.66 is the right number.

7b4690c515 * Source/opal/OpalFontInfo.m: Move font space to user space conversion 
to a separate method. Implement -glyphIsEncoded:, -advancementForGlyph:,
-glyphForCharacter:, -glyphWithName:.

For -boundingRectForGlyph:, and -widthOfString:, return fake, fixed
values.
* Source/opal/OpalContext.m: Fix -isDrawingToScreen implementation;
it now returns YES. This has the unfortunate side effect of breaking
image drawing... but, on the positive side, causes NSLayoutManager
to make calls to GSShowGlyphsWithAdvances in batches of up to
16 glyphs, instead of one at a time...!
* Source/opal/OpalGState.m: Implement -GSSetFont:, and make
-GSShowGlyphsWithAdvances: call CGContextShowGlyphsWithAdvances

Overall state is glyphs are drawn.. they appear upside down,
and the glyph runs only seem to draw at (0, 0).
