* Correctly adjust clip regions that lie offscreenChet Haase2012-10-161-3/+14
| | | | | | | | | | We were clamping the x/y location of the scissor to 0,0, but not adjusting the width/height appropriately. This fix adjusts width/height and also clamps them to 0 to correctly clip out offscreen operations. Issue #7221524 Top left and top right portions of the screen blanks out after some time Change-Id: I47f23336ea612409ed86652b9a68e272819ef00e
* Work around a possible driver bugRomain Guy2012-10-071-0/+1
| | | | | | | | | | Bug #7296475 When re-enabling the scissor the driver seems to ignore the already existing scissor box. This change resets the scissor box when the test state changes. Change-Id: I3a68433164f99d21fbab769a26c56fe416c1539a
* Fix texture corruptionChet Haase2012-09-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | When memory gets low on a device, activities flush everything they can. Hardware-accelerated activites, such as Launcher, flush GL resources and destroy the GL context. However, some resources were still hanging around, due to deferred destruction policies (we don't delete layers until the DisplayLists they are in are finalized, to ensure we don't deref deleted objects). This meant that we were referring to obsolete GL data in these objects. in particular, it meant that we might come around later, after a new GL context was created, and delete a texture object that was incorrect. We use the layer's "texture id" to refer to the texture underlying the layer. But if there's a new GL context, then this texture ID is no longer valid, and we may be deleting the texture that a different object (layer, icon, whatever) is referring to, because the driver may return that same ID under the new GL context. The fix is to more aggressively delete things that we know will not be used again when the GL context is destroyed. In particular, we delete all resources being used by all DisplayLists at GL context destruction time.

* Improve rendering speed by disabling scissor testsRomain Guy2012-07-131-1/+26
| | | | | | | | | | | | This change improves execution of display lists, particularly on tiled renderers. The goal is to disable the scissor test as often as possible. Drawing commands are rarely clipped by View bounds so most of them can be drawn without doing a scissor test. The speed improvements scale with the number of views and drawing commands.

| | | | | | | | | | | Bug #3413433 This change will be beneficial to Launcher to avoid hiccups when swiping pages of icons. When a layer is discarded, it is kept in the layers pool instead of being destroyed right away. This favors memory reuse over allocations. Change-Id: Ifb6944ba83d6ceb67c331527c0827b26ce648eb1

| | | | | | | | | | The new implementation relies on OpenGLRenderer's existing layer code instead of duplicating it. The new code is much cleaner, with simpler and better APIs and allows tracking of drawn regions inside layers. Region tracking is not yet enabled but this will be done in a future CL.

| | | | | | | | | | This change detects what area of a layer was drawn into and generates a mesh to match this area exactly.
