* Graph Region: Address overflow issue using GL2ES3 integer indices (WIP...); ↵Sven Gothel2023-02-246-41/+209
| | | | | | | | | | | | | | | Ease GLArrayData* buffer growth. Using integer indices, i.e. GL_UNSIGNED_INT, requires us to pass a GLProfile 'hint' to the GLRegion ctor. Region.max_indices is computed in this regard and used in Region.addOutlineShape(). TODO: If exceeding max_indices, the code path needs some work. Buffer growth is eased via GLArrayData using its golden growth ratio and manually triggering growth before processing all triangles in Region.addOutlineShape(). +++ TextRegionUtil static drawText() won't clear passed Region anymore, caller has to do this if so intended.
* GLArrayData*: Expose reserve() for total elementCount and growIfNeeded() for ↵Sven Gothel2023-02-242-37/+69

* GLArrayData*: Shorten methods (*API Change*), use proper constructor and ↵Sven Gothel2023-02-2410-250/+274
| | | | | | | | | | | | | finalize immutables, add growthFactor (default golden ratio 1.618), add getCapacity*() and printStats(..) The growthFactor becomes essential for better growth behavior and can be set via setGrowthFactor(). The other changes were merely to clean up the GLArrayData interface and its 4 implementations. Not great to change its API, but one name was misleading ['getComponentCount' -> 'getCompsPerEleme'], so overall .. readability is enhanced. Motivation for this change was the performance analysis and improvement of our Graph Curve Renderer.
* Graph Font: Fix TypecastRenderer TTF corner-case: Prefer initial segment's ↵Sven Gothel2023-02-231-36/+68
| | | | | | | | | | moveTo (start) to be onCurve One of the FreeSerif fonts starts a new segment with two off-curves, where the mid-point is not onCurve. Here we have to test whether the previous (point-1 or in code: point_m) is onCurve and simply start our 'turtle' making the shape there ..
* FFMPEGMediaPlayer: Add implementation update for FFmpeg version 4.* (Debian ↵Sven Gothel2023-02-2314-796/+639
| | | | | | | | | | | | | | | | | | | | | | | 11), 5.* (Debian 12) and 6.* (Current Development trunk) From here on, libav support has been dropped. Required FFmpeg libraries to be fully matched by their major runtime- and compiletime-versions are: - avcodec - avformat - avutil - swresample Library avdevice is optional and only used for video input devices (camera). Library avresample has been removed, since FFmpeg dropped it as well in version 6.* and swresample is preferred for lower versions. The matching major-versions of each library to the FFmpeg version is documented within FFMPEGMediaPlayer class API-doc. Each implementation version uses the non-deprecated FFmpeg code-path and compilation using matching header files is warning-free.

* 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 Gothel2023-02-176-114/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
