public abstract void	drawMesh(BasicTexture tex, int x, int y, int xyBuffer, int uvBuffer, int indexBuffer, int indexCount)
public abstract void	drawMixed(BasicTexture from, int toColor, float ratio, int x, int y, int w, int h)
public abstract void	drawMixed(BasicTexture from, int toColor, float ratio, android.graphics.RectF src, android.graphics.RectF target)
public abstract void	drawRect(float x1, float y1, float x2, float y2, GLPaint paint)

public abstract void	drawTexture(BasicTexture texture, android.graphics.RectF source, android.graphics.RectF target)
public abstract void	drawTexture(BasicTexture texture, float[] mTextureTransform, int x, int y, int w, int h)
public abstract void	dumpStatisticsAndClear()
public abstract void	endRenderTarget()
public abstract void	fillRect(float x, float y, float width, float height, int color)
public abstract float	getAlpha()
public abstract void	getBounds(android.graphics.Rect bounds, int x, int y, int width, int height) Gets the bounds given by x, y, width, and height as well as the internal matrix state. There is no special handling for non-90-degree rotations. It only considers the lower-left and upper-right corners as the bounds. param bounds The output bounds to write to. param x The left side of the input rectangle. param y The bottom of the input rectangle. param width The width of the input rectangle. param height The height of the input rectangle.
public GLId	getGLId()
public abstract void	initializeTexture(BasicTexture texture, android.graphics.Bitmap bitmap) Initializes the texture to a size by calling texImage2D on it. param texture The texture to initialize the size. param bitmap The bitmap to initialize the bitmap with.
public abstract void	initializeTextureSize(BasicTexture texture, int format, int type) Initializes the texture to a size by calling texImage2D on it. param texture The texture to initialize the size. param format The texture format (e.g. GL_RGBA) param type The texture type (e.g. GL_UNSIGNED_BYTE)
public abstract void	multiplyAlpha(float alpha)
public abstract void	multiplyMatrix(float[] mMatrix, int offset)
public abstract void	recoverFromLightCycle() After LightCycle makes GL calls, this method is called to restore the GL configuration to the one expected by GLCanvas.
public abstract void	restore()
public abstract void	rotate(float angle, float x, float y, float z)
public abstract void	save()
public abstract void	save(int saveFlags)
public abstract void	scale(float sx, float sy, float sz)
public abstract void	setAlpha(float alpha)
public abstract void	setSize(int width, int height)
public abstract void	setTextureParameters(BasicTexture texture) Sets texture parameters to use GL_CLAMP_TO_EDGE for both GL_TEXTURE_WRAP_S and GL_TEXTURE_WRAP_T. Sets texture parameters to be GL_LINEAR for GL_TEXTURE_MIN_FILTER and GL_TEXTURE_MAG_FILTER. bindTexture() must be called prior to this. param texture The texture to set parameters on.
public abstract void	texSubImage2D(BasicTexture texture, int xOffset, int yOffset, android.graphics.Bitmap bitmap, int format, int type) Calls glTexSubImage2D to upload a bitmap to the texture. param texture The target texture to write to. param xOffset Specifies a texel offset in the x direction within the texture array. param yOffset Specifies a texel offset in the y direction within the texture array. param format The texture format (e.g. GL_RGBA) param type The texture type (e.g. GL_UNSIGNED_BYTE)
public abstract void	translate(float x, float y, float z)
public abstract void	translate(float x, float y)
public abstract boolean	unloadTexture(BasicTexture texture)
public abstract int	uploadBuffer(java.nio.FloatBuffer buffer) Generates buffers and uploads the buffer data. param buffer The buffer to upload return The buffer ID that was generated.
public abstract int	uploadBuffer(java.nio.ByteBuffer buffer) Generates buffers and uploads the element array buffer data. param buffer The buffer to upload return The buffer ID that was generated.
