A lot of different fixes.
A lot of issues still there:
1) if we only render part of the tree, tree isomorphism will sometimes not work correctly2) when we change Effects that are inside Trees mid-render, even if we detach() the affected parts of the Tree first, for the last frame the new Effects will be used...
Simplify yesterday's refactoring.
Major: change of API.
Split DFramebuffer into Framebuffer and Screen; introduce the 'DistortedInputSurface' and 'DistortedOutputSurface' interfaces.
Some fixes for issues discovered by the Multiblur app.
Beginnings of the 'Multiblur' app.
BLUR: implemented caching of the BLUR kernels.
Minor progress with Gaussian. Still need to cache the Weights and Offests tables.
Separable Gaussian Blur with linear sampling done.
Linear sampling implemented - i.e. blurring by a (2N+1)x(2N+1) gaussian kernel (centeral pixel + N pixels in each direction) requires exactly 2N + (N%2==1 ? 4:2) texture fetches.
Precompute the standard normal distribution.
minor.
Separable Box blur fully works now!
Separable Box blur (almost) works.
Small progress with Blur.
Try using OpenGL ES 3.0 everywhere (but if device does not support it, try creating 2.0 context - this is important because of the emulator!)
improve Postprocessing; new icon; minor things.
Postprocessing effects: remove support for Center
Progress with getting Mesh'es bounding rectangle. Still doesn't quite work yet (visible : 'Cubes' app with a 0111 Mesh)
Correct a bug with Postprocessing Shortcut.
Move more intelligence to EffectQueuePostprocess.
Progress with multi-program rendering.
Naive implementation of blur works now!
Blurred image visible now!
Further progress with Postprocessing. Now the missing bits are:
- implement Distorted.getFBO()- implement Distorted.clean()- improve compilation of DistortedPrograms so that the NUM_POSTPROCESSING and names of POSTPROCESSING effects will be #defined.
Minor.
progress with Postprocessing.
Beginnings of support for postprocessing Effects.
