* Fixes for 64bit in libhwuiKévin PETIT2014-02-211-1/+1
| | | | | | | | | Using reinterpret_cast allows conversions between pointer types and integers which don't have the same size. The corresponding flags is -Wint-to-pointer-cast. Change-Id: I8ff0c79d235fa6d07b8d9305edc185d946d5133d Signed-off-by: Kévin PETIT <kevin.petit@arm.com>
* Batch 9-patches in a single mesh whenever possibleRomain Guy2013-06-211-1/+4
| | | | | | | | | | This change also fixes the way batched bitmaps were handled inside a layer. The layer is now correctly dirtied to minimize the amount of pixels to blend. Fix alpha, mode and opaque computations for DrawPatchOp. Change-Id: I1b6cd581c0f0db66c1002bb4fb1a9811e55bfa78

* Introduce PixelBuffer API to enable PBOsRomain Guy2013-04-111-0/+163
PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform asynchronous texture uploads to free up the CPU. This change does not enable the use of PBOs unless a specific property is set (Adreno drivers have issues with PBOs at the moment, Mali drivers work just fine.) This change also cleans up Font/FontRenderer a little bit and improves performance of drop shadows generations by using memcpy() instead of a manual byte-by-byte copy. On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance behaves like a simple byte array. The extra APIs introduced for PBOs (map/unmap and bind/unbind) are pretty much no-ops for CPU pixel buffers and won't introduce any significant overhead. This change also fixes a bug with text drop shadows: if the drop shadow is larger than the max texture size, the renderer would leave the GL context in a bad state and generate 0x501 errors. This change simply skips drop shadows if they are too large. Change-Id: I2700aadb0c6093431dc5dee3d587d689190c4e23
