Changes

Enable GitHub sponsor button

Adds a FUNDING.yml file that enables a sponsor button to become visible in the top of the repository. This button links to the sponsor page and thus makes the possibility to donate easier and more visible.

See https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/displaying-a-sponsor-button-in-your-repository

Add support for riscv64 architecture

Use DPI scaling to scale drawn fonts.

Add support for Linux/ppc64le architecture

Add swt 4.26 for gtk-linux-ppc64le

This is required for the Linux/ppc64le target to build.

README.md: Adding JogAmp History & Milestones, ...

README.md: Shorten gl4java section

Adopt to GlueGen commit 952e0c1f83c9e0583a97d39988a6ba1428911c8c

To limit growing code due to GlueGen's more capable new `Struct` emitter (more supported setter),
`Struct` with intended read-only access have been marked `ImmutableAccess` in their GlueGen config file.

Produced code with above setting compared with pre-GlueGen change is reduced
while also having dropped all of the JNI calls retrieving `Struct` values.
Only calls to function-pointer produced JNI methods, of course.

Adopt to GlueGen Struct API Change get/set array arguments

NativeSignatureJavaMethodBindingEmitter: Adopt to GlueGen changes

README.md: JogAmp History & Milestones: Added Java3D + Ardor3D, added GlueGen JavaCallback (grouped)

Add {GL, GLContext}.getDefaultDrawBuffer() to complement getDefaultReadBuffer()

README: Add Harvey to contributors (missed him, sorry)

Graph: Minor cleanup: TextRegionUtil: Fix API doc references; RegionRenderer.enable(..) merge '!enable' branch, fix API doc

GraphUI: Add Shape.getSurfacePort(..): Similar to getSurfaceSize(..) but returns the whole Recti viewport of the shape

GLStateTracker: Encapsulate PixelStateMap for PixelStorei states (prepare for tracking of blending states)

GLStateTracker: Add tracking of blending states (part-1)

Add Graph/GraphUI UISceneDemoU01a, showcase integration and multiple projection settings

Graph GLRegion.create(..): Expose variant with custom pass2TexUnit for VBAA (default texture unit is 0)

Graph RenderState: Initialize colorStatic w/ alpha=1 to avoid invisible rendering if no static color has been set

Shader either uses just colorStatic or multiplies it w/ the color-stream value

Graph RegionRendered.init(..): Disable renderer (and shader programs etc) to avoid side-effects. Usually called @ GLEventListener.init(..)

Graph Add {GLRegion, GraphShape}.setTextureUnit(int): Allowing to set texture unit after ctor

UISceneDemoU01a: Destory textRegion @ dispose

Update tests script .. (consolidate GraphUI demo lines)

Graph: Simplify RegionRenderer API by exposing common RenderState methods (and fwd 'em to RenderState aggregate)

Graph RegionRenderer.destroy(): Detach RenderState from GL instance

Remove potential leak

Graph RenderState: Initialize colorStatic w/ all white (1,1,1,1) if color-channel is used and no static-color set

Commit a973324a75b55b722caa755a7a573be849d997e4 was setting the alpha to 1,
which avoids the 'discard' in the shader.
This at least gave us a black color ;-)

However, the shader modulates the color, i.e. color-channel * color-static,
therefor we need an all-white color-static as default
if user only sets the color-channel.

Graph TextRegionUtil.drawString3D(..): Redefine 'rgbaColor' semantics: Either fill color-channel with value if used and set static-color to white - or just set static color channel with value.

Have the given rgbaColor to definitely setting the text color regardless whether a color channel is used or not.
Note: Using a color-channel is more expensive (color value per vertex) and should only be required if mixing
colors within one region!

Also removes potential side-effects if color-channel is used but user forgets to set the static value properly.

Graph / GraphUI Demos: Don't use the color-channel if not required (mixing colors within one region)

Note, commit bb6ee81bc5514663bb7b22224fcdd5ba34a51ac6
relaxes the requirement for using a color-channel.

Bug 1441 - Fix ARB_multi_draw_indirect: Belongs to GL4, glMultiDrawElementsIndirect shall only have VBO indirect access

Bug 1441, 852: Annotate ARB_draw_indirect dual sourcing, remove redundant manual declarations

Update README.md, index.html (Graph/GraphUI, references) and add OpenGL_API_Divergence.md

README/index: Fix link to OpenGL_API_Divergence.html

Test Bug1310: Remove and re-add a GLJPanel from its Swing parent (working)

Also tested with Sofr-HiDPI on Linux using GDK_SCALE=2

README/index: 'Graph UI' -> GraphUI

scripts/tests.sh: Add TestGLJPanelReadd01Bug1310AWT

Untangle joal from build requirements as introduced via new jogl-demos

To enjoy the UISceneDemo20 demo, joal shall exist at its usual location.
However, pass build if not available.
Also drop ant + junit from demos.

- Rename jogl-demo-android.{jar,apk} -> jogl-demos-android.{jar,apk}

- New demo classpath
  - Add non-joal demo classpath
  - Add joal demo classpath.
  - Drop junit + ant from both

- Remove joal from junit compile path.

- Build test: demo compilation (Java + Android)
  - Drop joal dependencies if not available

README: Add Mathieu Féry, who enhanced GlueGen

Bug 1450: Remove nativewindow's drm-gbm GlueGen config's manual constant definitions, now properly passed from GlueGen

GLMediaPlayer: Show more reasonable DEBUG output in factory; Impl initGL(GL) shall handle null streamWorker, i.e. when using NullGLMediaPlayer

Graph TextRegionUtil.drawString3D(..): Allow null `rgbaColor` w/o color-channel again, was enforced to be set in commit bb6ee81bc5514663bb7b22224fcdd5ba34a51ac6

FontViewListener01/TestTextRendererNEWT21: Use 30 pixelPerCell (total w/ gap) for test case to compare pixel-by-pixel

Add GraphUI to javadoc source path

Fix typo of commit d8e086e0321ef1021f4a7810d7bfd2306c4ac725: jogl{s->}-demo{->s}-android
