* Source/opal/OpalContext.m (-GSSetDevice:::): Get height form
surface if no y value is given.
* Source/opal/OpalSurface.m: Rewrite to handle the case where
device is not set.
In Quartz, the "graphics port" bound to an NSGraphicsContext (subclassed
by OpalContext) is a CGContext. We currently initialize one in
OpalSurface if it does not exist, however we do not allow the client to
initialize a graphics context with a custom graphics port, which should
be allowed. This commit enables this feature.
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).
