Po Lu 4e46df9651 Optimize damage region tracking under Android
* java/org/gnu/emacs/EmacsDrawLine.java (perform):

* java/org/gnu/emacs/EmacsDrawRectangle.java (perform): Call
damageRect with integer coordinates in lieu of consing a new
Rect.

* java/org/gnu/emacs/EmacsDrawable.java (damageRect) <IIII>:
Declare a new variant of damageRect, accepting four integers
designating the extents of the damage rectangle.

* java/org/gnu/emacs/EmacsPixmap.java (damageRect) <IIII>: New
stub.

* java/org/gnu/emacs/EmacsView.java (damageRect) <IIII>:
Implement this overloaded variant of damageRect.

* java/org/gnu/emacs/EmacsWindow.java (damageRect): Ditto.

* src/android.c (android_init_emacs_drawable)
(android_init_emacs_window): Move search for `damageRect' to
android_init_emacs_window.
(android_damage_window): Call IIII variant of `damageRect' to
avoid consing a new rectangle.  Ameliorate dynamic method
dispatch overhead.

This directory holds the Java sources of the port of GNU Emacs to
Android-like systems, along with files needed to create an application
package out of them.  If you need to build this port, please read the
file INSTALL in this directory.

The ``org/gnu/emacs'' subdirectory contains the Java sources under the
``org.gnu.emacs'' package identifier.

``AndroidManifest.xml'' contains a manifest describing the Java
sources to the system.

The ``res'' directory contains resources, mainly the Emacs icon and
several ``boolean resources'' which are used as a form of conditional
evaluation for manifest entries.

`emacs.keystore' is the signing key used to build Emacs.  It is kept
here, and we encourage all people redistributing Emacs to use this
key.  It holds no security value, and otherwise it will be impossible
to install different builds of Emacs on top of each other.

Please keep the Java code indented with tabs and formatted according
to the rules for C code in the GNU coding standards.  Always use
C-style comments.

Refer to the file `admin/notes/java' in the toplevel directory of the
Emacs distribution or repository for specifics regarding writing Java
code for Emacs and the organization of the Android port.
