Pass2-AA, revise Pass2 AA Quality parameter ..
Misc:
- Graph VBORegion2PVBAAES2: Drop unused FBO rescale
- Move MIN/MAX QUALITY/SAMPLE from GraphUI Scene -> Graph Region
+++
Quality -> Pass2 AA Quality
- Drop quality field in region
- Pass quality to GLRegion.draw(..) similar to sampleCount
for dynamic shader and switch
- TODO: Pass quality parameter in TextRegionUtil's functions
Fix RegionRenderer Shader Mapping
- Use ShaderKey class to properly implement the hash value and equals method
- For this, TextureSequence.getTextureFragmentShaderHashID() has been added
to provide actual shader-snippet for the equals function
- All required criterias are included in the hash value and equals method
Fix AABBox Clipping for Pass-2 AA
- Clipping in pass2-AA must happen in pass2 on actual gcu_PMVMatrix01 (not ortho)
+++
GraphUI GraphShape
- Rename: [get,set]{->AA}Quality()
GraphUI Scene
- Rename: mark{All->}ShapesDirty(), set{AllShapes->}Sharpness(), set{AllShapes->AA}Quality()
- Fix setSampleCount(..), i.e. markStatesDirty() not markShapesDirty()
- Fix setAAQuality(), markShapesDirty() and markStatesDirty(): Use forAll(..) to traverse through all shapes and groups.
GraphUI Group
- Add setFixedSize()
- Add setClipOnBox()
- Document setRelayoutOnDirtyShapes(), isShapeDirty()

- GLSL vertex shader sets smooth varying 'gcv_ClipBBoxCoord' w/ Mv multiplied vertex-coord
- RegionRenderer.setClipBBox(AABBox) expects a pre-multiplied Mv AABBox covering an independent area, not per Shape/Region.
- This works as expected with moving/scaling of each Shape/Region etc

min/max vec3 as convenient using Graph/GraphUI produced AABBox
USE_AABBOX_CLIPPING
- Conditional compilation w/ macro 'USE_AABBOX_CLIPPING'
- gcv_ClipBBoxCoord smooth varying setup in vertex shader
- fragment shader clips via branch
if( is_inside(gcv_ClipBBoxCoord, gcu_ClipBBox[0], gcu_ClipBBox[1]) < 0.5 ) { CLIP }
- clipping via discard or alpha=0 in case of buggy-discard.
Other optimization:
- Drop gcv_ColorTexExt, fragment-shader uses gcu_ColorTexBBox[2] directly (flat)
- Simplified gcv_ColorTexCoord smooth varying equation in vertex shader.

aspect-ratio, letter-boxed or zoomed (config) + Bug 1466 Fix color mixing
Bug 1465: Region currently simply bloats a given texture to its region AABBox,
which renders textures with the wrong aspect ratio.
Add facility to program the texture-coordinates to either letter-box
or scaled-up (and cut) true aspect-ratio.
Default shall be zoom (scale-up and cut),
but user shall be able to set a flag in the Region for letter-box.
Have the shader clip texture coordinates properly,
best w/o branching to soothe performance.
See functions.glsl
+++
Bug 1466: Current color mix: texture * color_channel * color_static
is useless in GraphUI.
color_static shall modulate the texture, which works.
But in case of color_channel (attribute/varying)
we want it to be mixed so it can become the more dominant color
for e.g. a border.
Desired is:
color = vec4( mix( tex.rgb * gcu_ColorStatic.rgb, gcv_Color.rgb, gcv_Color.a ),
mix( tex.a * gcu_ColorStatic.a, 1, gcv_Color.a) );

TextureSequence to Region (Demo: TextureButton)
Cleanup shader-program location/data update
- GLUniformData:
- Allow lazy data setup, as used for
RenderState.ProgramLocal, see below
- RenderState
- Separate data (pmv, weight, colorStatic) from
program-local uniforms -> add class ProgramLocal.
Reduces uniform location lookups, since
ProgramLocal is bound to Region impl.
- ProgramLocal.update(..) needs to write uniform data always,
since data is being used in multiple programs!
- No 'dirty' tracking possible, removed - see above.
- RegionRenderer
- Fix shader-selection: 2-pass programs differ from 1-pass!
- No shader-setup at init
+++
Add COLORTEXTURE + TextureSequence to Region
- Create color-texture coords in vertex-shader via region's bounding box (pass-1)
- Use color-texture unit in pass-1 if enabled (own shader program)
- Use TextureSequence in Region impl. providing all required data (unit + texture-name)
- Demo: TextureButton (a UIShape)

in shader; Update attributes and uniforms manually, drop ShaderState;
- ShaderCode
- add int insertShaderSource(int shaderIdx, int position, Class<?> context, String path)
- insertShaderSource(..): pos==-1 -> append code
- VectorUtil
- add isVec3InTriangle3(..., float epsilon)
- add testSeg2SegIntersection(..., float epsilon)
- add testTri2SegIntersection(..., float epsilon)
- AffineTransform: Return result for chaining
- Font
- Add pixel precise 'getPointsBounds(final AffineTransform transform, CharSequence string, float pixelSize)'
- Rename getString*() -> getMetric*()
- OTGlyph: Release _points field, no more used
-
- Graph Triangulation
- Count additional vertices in: Triangulator, CDTriangulator2D
- OutlineShape:
- Allow skipping of 'transformOutlines2Quadratic', i.e. allow tagging
OutlineShape to be quadratic_nurbs via 'setIsQuadraticNurbs()'
- Clarify cleanup ot outlines in same method 'cleanupOutlines()'
- Count additional vertices ..
- Graph Shader:
- Start splitting and segmenting shader code for:
- pass1 / pass2
- features, i.e. sampleCont, color-channel, ..
