blitCopy()
@fn virtual void LCD16bpp::blitCopy(const uint8_t* sourceData, Bitmap::BitmapFormat sourceFormat, const Rect& source, const Rect& blitRect, uint8_t alpha, bool hasTransparentPixels); Blits a 2D source-array to the framebuffer while converting the format. Blits a 2D source-array to the framebuffer perfoming alpha-blending (and tranparency keying) as specified. Performs a software blend if HAL does not support BLIT_COPY_WITH_ALPHA and alpha != 255. LCD16 supports source data formats: RGB565 and ARGB8888.

drawTextureMapScanLine()
@fn virtual void LCD16bpp::drawTextureMapScanLine(const DrawingSurface& dest, const Gradients& gradients, const Edge* leftEdge, const Edge* rightEdge, const TextureSurface& texture, const Rect& absoluteRect, const Rect& dirtyAreaAbsolute, RenderingVariant renderVariant, uint8_t alpha, uint16_t subDivisionSize); Draw scan line. Draw one horizontal line of the texture map on screen. The scan line will be drawn using perspective correct texture mapping. The appearance of the line is determined by the left and right edge and the gradients structure. The edges contain the information about the x,y,z coordinates of the left and right side respectively and also information about the u,v coordinates of the texture map used. The gradients structure contains information about how to interpolate all the values across the scan line. The data drawn should be present in the texture argument. The scan line will be drawn using the additional arguments. The scan line will be placed and clipped using the absolute and dirty rectangles The alpha will determine how the scan line should be alpha blended. The subDivisionSize will determine the size of the piecewise affine texture mapped lines.
