* Forget the name of a texture after freeingRomain Guy2012-05-141-4/+8
| | | | | | | | | | | | | | | | | Bug #6408362 FontRenderer allocates large font textures when more room is needed to store all the glyphs used by an application. Thse large textures are the first to be freed when memory needs to be reclaimed by the system. When freeing a texture, the renderer would however not set the texture name to an invalid name, leading future allocations to be performed on the same texture name. That name could have by then be recycled by the driver and returned by a call to glGenTexture and used to create an entirely different texture. This would cause the font renderer to point to the wrong texture, thus leading to the "corruptions." Change-Id: I8a1e80e5b79e8f21d1baf5320c090df4f2066cd4

* Use a status_t return type for GL functorsRomain Guy2012-03-261-1/+1
| | | | | | | | | WebView needs more fine-grained control over the behavior of the framework upon execution of the display lists. The new status_t allows WebView to requests its functor to be re-executed directly without causing a redraw of the entire hierarchy. Change-Id: I97a8141dc5c6eeb6805b6024cc1e76fce07d24cc

* Plug memory leak.Romain Guy2012-03-211-0/+2
| | | | | | | | | | | | Bug #6196903 Whenever a memory flush happens, the GL renderer discards some or all of its font caches. Each font cache holds an array of vertex indices that was initially designed to have the same life cycle as the process. This changed when memory flushes were introduced but this array was never taken care of in the destructor. Change-Id: Ief124f609ea55b671c0a9b43637d9e013629ebaa

* De-allocate caches for large glyphs when trimming memoryChet Haase2011-12-161-2/+39
| | | | | | | | | | | | | Currently, font renderers eliminate some texture caches when memory is trimmed. This change makes it go further by eliminating the large-glyph caches for all font renderers. These caches are only allocated as needed, but continue to consume large amounts of memory (CPU and GPU) after that allocation. De-allocating this memory on a trim operation should prevent background apps from holding onto this memory in the possible case that they have allocated it by drawing large glyphs.

* Fix issues from recent glyph caching changeChet Haase2011-12-151-19/+31
| | | | | | | | | | | | | There were 2 issues remaining after a recent change to support glyph caching from multiple textures: - memory in the GPU for all textures was being allocated automatically. This is now lazy, being allocated only when those textures are first needed. - filtering (applied when a rendered object is transformed) was ignoring the new multiple-texture structure. Filtering should be applied correctly whenever we change textures. Change-Id: I5c8eb8d46c73cd01782a353fc79b11cacc2146ab

| * Make glyph cache more flexibleChet Haase2011-12-131-87/+142
| | | | | | | | | | | | | | | | | | | | Some GPU architectures could not handle the previous implementation of our glyph cache. Frequent uploads would cause memory problems in the GPU and eventually a crash due to these memory issues. The solution is to move to a system of several, smaller caches instead of one monolythic cache for all glyphs. Change-Id: I0fc7a323360940d16d5a33eeb33abfab194c5920

* Fix problem with glyph cache and textScaleX propertyChet Haase2011-03-021-6/+9
| | | | | | | | | | Glyphs drawn with paints that had different textScaleX values were not being recognized as different, so the glyph cache was being used regardless of different scaleX values. This change adds the scaleX attribute to the native Font object to allow the cache to distinguish between this difference and cache accordingly. Change-Id: I5d8fc26d47460b27dc8e373a473d46b2f1b8dc30

| | | | | | | | | | | | When an app tries to render a bitmap or path larger than the GPU's maximum texture size, the drawing command is ignored and a warning is logged. This change also makes texture drawing more robust by catching potential errors during texture creation. This change also fixes a crash in the FontRenderer.
