* Graph TextRegionUtil: Fix HashMap (font,text)->GLRegion: Preserve key data ↵Sven Gothel2023-02-191-20/+40

* Graph Font: Add 'name' to Glyph; Drop erroneous Glyph ID_SPACE, ID_CR manual ↵Sven Gothel2023-02-193-52/+43
| | | | | | | | | | | | | | mapping, rely on no-shape for 'space' non-contour. Drop erroneous Glyph ID_SPACE, ID_CR to rely on no-shape for 'space' non-contour resolves different cmap-mappings of fonts, not following 'some std'. Hence getGlyph(glyph_id) no more uses the `font.getGlyph(Glyph.ID_UNKNOWN)` shape, but a null-shape as intended and using the hmtx and hhea table values for asvance and bounds. This fixes 'space' spacing in general and specifically FreeSerif-Regular and the like. This path also simplifies processing/layout of glyphs in process(..) and get*BoundsFU(..).

* | Graph: Fix Loop.initFromPolyline()'s Winding determination, document Winding ↵Sven Gothel2023-02-1711-157/+654
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rules for OutlineShape and add get/setWinding in Outline Loop.initFromPolyline()'s Winding determination used a 3-point triangle-area method, which is insufficent for complex shapes like serif 'g' or 'æ'. Solved by using the whole area over the Outline shape. Note: Loop.initFromPolyline()'s Winding determination is used to convert the inner shape or holes to CW only. Therefor the outter bondary shapes must be CCW. This details has been documented within OutlineShape, anchor 'windingrules'. Since the conversion of 'CCW -> CW' for inner shapes or holes is covered, a safe user path would be to completely create CCW shapes. However, this has not been hardcoded and is left to the user. Impact: Fixes rendering serif 'g' or 'æ'. The enhanced unit test TestTextRendererNEWT01 produces snapshots for all fonts within FontSet01. While it shows proper rendering of the single Glyphs it exposes another Region/Curve Renderer bug, i.e. sort-of a Region overflow crossing over from the box-end to the start.

* Font/Graph, {Font, Glyph}/Typecast: Add kerning and expose values in ↵Sven Gothel2023-02-1022-354/+1019
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | original font-units (FU) to have them scaled later ( fu * pixelScale / unitsPerEM ) Scaling from font-units (funits, or FU) is now performed by the renderer itself, i.e. applying the scale-factor 'fontPixelSize / font.getMetrics().getUnitsPerEM()' to the PMV matrix to render the whole graph GLRegion. This finally provides proper device and resolution independent font utilization. Further, preliminary kerning has been added. +++ Also ... TypecastFont: - getGlyphID(..) getGlyph(..) enforce symbol mapping to Glyph.ID_SPACE Glyph.ID_CR, as some fonts ave an erroneous cmap (FreeSerif-Regular) - add getKerning(..) TODO: Add binary search - Set TypecastFont.USE_PRESCALED_ADVANCE := false, i.e. dropping all prescaled pixel-sized advance values mapped to font pixel-size as we utilize font-units only for later uniform scaling. - Drop virtual getPixelSize() and add static FontScale.toPixels(..) - Add fullString() for debugging purposed, including some font tables
