* Use float textures to render gradients when possibleRomain Guy2013-04-051-1/+24
| | | | | | | | | | | Float textures offer better precision for dithering. In addition this change removes two uniforms from gradient shaders. These uniforms were used to dither gradients but their value is a build time constant. Instead we hardcode the value directly in the shader source at compile time.

* Remove unnecessary & uninitialized variableRomain Guy2013-01-031-2/+0
| | | | | | | | | | | Bug #7728929 The uninitialized variable was taken into account to compute the hash of gradient cache entries, thus causing cache corruptions and sometimes infinite loops (it would also cause the cache to fill up.) Change-Id: Ic807a9bf901888b121a6a781a81dafc33075ed2a
* Use LruCache instead of GenerationCache in libhwuiRomain Guy2012-11-291-17/+29

* Improve gradientsRomain Guy2012-07-311-20/+21
| | | | | | Avoid using textures for common gradients (two stops from 0.0 to 1.0) Change-Id: Iff55d21b126c8cfc4cfb701669f2339c8f6b131a
* Clamp gradient textures to max GL texture sizeRomain Guy2012-07-201-0/+4

* Add missing includes for Mutex.hDerek Sollenberger2012-03-051-0/+1
| | | | | | | The missing header was being transitively included through a Skia header which is being removed. Change-Id: I5a65bae076027951fe07d1e7eecd4732124fb0e4
* Make sure we correctly copy caches keys.Romain Guy2011-08-121-16/+27
| | | | | | Bug #5136067 Change-Id: I366e840bef44415436dc7b13d89cfb610feed663
* Prevent crash when purging the gradients cache.Romain Guy2011-08-081-2/+2
| | | | | | Bug #5133876 Change-Id: I3d1fa4e29498044796d725337ac93e6a1e8f0bcb
* Reduce the amount of data cached by the gradients cache.Romain Guy2011-08-011-24/+70

* Free resources only from the GL context thread.Romain Guy2010-11-111-6/+14
| | | | | | | | | | Bug #3179882 Resources were freed following garbage collections on a worker thread. This worker thread had no EGL context, which would cause the renderer to incorrectly assume that the memory was liberated. Change-Id: Ifdb51f94ddf42641e8654522787bfac532976c7c
* Optimize FBO drawing with regions.Romain Guy2010-11-021-3/+3
| | | | | | | | | This optimization is currently disabled until Launcher is modified to take advantage of it. The optimization can be enabled by turning on RENDER_LAYERS_AS_REGIONS in the OpenGLRenderer.h file. Change-Id: I2fdf59d0f4dc690a3d7f712173ab8db3848b27b1
