The major things going on here:
- The MotionEvent API is now extended to included "pointer ID" information, for
applications to keep track of individual fingers as they move up and down.
PointerLocation has been updated to take advantage of this.
- The input system now has logic to generate MotionEvents with the new ID
information, synthesizing an identifier as new points are down and trying to
keep pointer ids consistent across events by looking at the distance between
the last and next set of pointers.
- We now support the new multitouch driver protocol, and will use that instead
of the old one if it is available. We do NOT use any finger id information
coming from the driver, but always synthesize pointer ids in user space.
(This is simply because we don't yet have a driver reporting this information
from which to base an implementation on.)
- Increase maximum number of fingers to 10. This code has only been used
with a driver that reports up to 2, so no idea how more will actually work.
- Oh and the input system can now detect and report physical DPAD devices.
If the output stream handler passed was not the A2DP output stream, the request was ignored instead of being forwarded downstream to hardware interface.
* changes:
Implement the jni bindings for Adapter2D. Fix a refcount bug in the native adapter implementation. Use adapters in Film to border the mipmaps.
* changes:
log opengl-call-with-no-context only once per thread, instead of for each function call
don't crash in Parcel when given a null (and therfore invalid) native_handle_t
there was several issues:
- when a surface was made non-current, the last frame wasn't shown and the buffer could stay locked
- when a surface was made current the 2nd time, it would not dequeue a new buffer
now, queue/dequeue are done when the surface is made current.
for this to work, a new query() hook had to be added on android_native_window_t, it allows to retrieve some attributes of a window (currently only width and height).
The current gralloc allocates buffer memory for render targets that will typically have NPOT dimensions. Assuming that the vendor driver supports converting the resulting NPOT android_native_buffer_t to a NPOT EGLImage, SurfaceFlinger calls glEGLImageTargetTexture2DOES(), and uses glGetError() to test whether the GL can support creating an EGL target texture with the specified NPOT EGLImage. If it is supported, the DIRECT_TEXTURE flag remains set, otherwise it is cleared.
Tangentially, if the driver advertises the GL_ARB_texture_non_power_of_two extension, the NPOT_EXTENSION flag is set, otherwise it is cleared.
If the driver supported creating an EGL target texture from a NPOT source EGLImage, it implicitly creates a NPOT texture. This does not need any glScalef() texture coordinate correction in LayerBase::drawWithOpenGL(). However, the same driver may not advertise the GL_ARB_texture_non_power_of_two extension nor generally support NPOT textures that were not derived from EGLImages. So SurfaceFlinger may flag only DIRECT_TEXTURE, not NPOT_EXTENSION.
Therefore, the test in LayerBase::drawWithOpenGL() should only perform the glScalef() if neither NPOT_EXTENSION or DIRECT_TEXTURE are flagged. Otherwise scaling is applied to NPOT EGL target textures when none is required.
It turns out we were not returning the density for anything retrieved from a
TypedArray... which basically means any bitmap references from a layout or style...!!!
This is now fixed.
Also fiddle with the density compatibility mode to turn on smoothing in certain situations,
helping the look of things when they need to scale and we couldn't do the scaling at
load time.
