+ * If forceTrueColour is true then we try to use a TrueColor visual - if
+ * requestedDepth is set then it must be of that depth, otherwise any depth
+ * will be used.
+ *
+ * Otherwise, we use the X server's default visual and colormap. If this is
+ * TrueColor then we just ask the RFB server for this format. If the default
+ * isn't TrueColor, or if useBGR233 is true, then we ask the RFB server for

+ * Interpolation:
+ * We calculate the distances from our point to the four nearest pixels, d1..d4.
+ * d(a,b) = sqrt(a�+b�) ~= 0.707(a+b) (Pythagoras (Taylor) expanded around (0.5;0.5))
+ *
+ * 1 wx 2
+ * *-|-* (+ = our point at (x,y))
+ * | | | (* = the four nearest pixels)
+ * wy --+ | wx = float(x) - int(x)
+ * | | wy = float(y) - int(y)
+ * *---*
+ * 3 4
+ * d1 = d(wx,wy) d2 = d(1-wx,wy) d3 = d(wx,1-wy) d4 = d(1-wx,1-wy)
+ * We now want to weight each pixels importance - it's vicinity to our point:
+ * w1=d4 w2=d3 w3=d2 w4=d1 (Yes it works... just think a bit about it)
+ *
+ * If the pixels have the colors c1..c4 then our point should have the color
+ * c = (w1*c1 + w2*c2 + w3*c3 + w4*c4)/(w1+w2+w3+w4) (the weighted average)
+ * but w1+w2+w3+w4 = 4*0.707 so we might as well write it as
+ * c = p1*c1 + p2*c2 + p3*c3 + p4*c4 where p1..p4 = (w1..w4)/(4*0.707)
+ *
+ * But p1..p4 are fixed point so we can just divide the fixed point constant!
+ * 8192/(4*0.71) = 2897 and we can skip 0.71 too (the division will cancel it everywhere)
+ * 8192/4 = 2048
+ *
+ * 020102: I changed the fixed-point representation for the variables in the weighted average
+ * to 24.7 to avoid problems with 32bit colors. Everything else is still 18.13. This
+ * does however not solve the problem with 32bit RGBA colors...

+ * Tight Encoding.
+ *
+ *-- The first byte of each Tight-encoded rectangle is a "compression control
+ * byte". Its format is as follows (bit 0 is the least significant one):
+ *
+ * bit 0: if 1, then compression stream 0 should be reset;
+ * bit 1: if 1, then compression stream 1 should be reset;
+ * bit 2: if 1, then compression stream 2 should be reset;
+ * bit 3: if 1, then compression stream 3 should be reset;
+ * bits 7-4: if 1000 (0x08), then the compression type is "fill",
+ * if 1001 (0x09), then the compression type is "jpeg",
+ * if 0xxx, then the compression type is "basic",
+ * values greater than 1001 are not valid.
+ *
+ * If the compression type is "basic", then bits 6..4 of the
+ * compression control byte (those xxx in 0xxx) specify the following:
+ *
+ * bits 5-4: decimal representation is the index of a particular zlib
+ * stream which should be used for decompressing the data;
+ * bit 6: if 1, then a "filter id" byte is following this byte.
+ *
+ *-- The data that follows after the compression control byte described
+ * above depends on the compression type ("fill", "jpeg" or "basic").
+ *
+ *-- If the compression type is "fill", then the only pixel value follows, in
+ * client pixel format (see NOTE 1). This value applies to all pixels of the
+ * rectangle.
+ *
+ *-- If the compression type is "jpeg", the following data stream looks like
+ * this:
+ *
+ * 1..3 bytes: data size (N) in compact representation;
+ * N bytes: JPEG image.
+ *
+ * Data size is compactly represented in one, two or three bytes, according
+ * to the following scheme:
+ *
+ * 0xxxxxxx (for values 0..127)
+ * 1xxxxxxx 0yyyyyyy (for values 128..16383)
+ * 1xxxxxxx 1yyyyyyy zzzzzzzz (for values 16384..4194303)
+ *
+ * Here each character denotes one bit, xxxxxxx are the least significant 7
+ * bits of the value (bits 0-6), yyyyyyy are bits 7-13, and zzzzzzzz are the
+ * most significant 8 bits (bits 14-21). For example, decimal value 10000
+ * should be represented as two bytes: binary 10010000 01001110, or
+ * hexadecimal 90 4E.
+ *
+ *-- If the compression type is "basic" and bit 6 of the compression control
+ * byte was set to 1, then the next (second) byte specifies "filter id" which
+ * tells the decoder what filter type was used by the encoder to pre-process
+ * pixel data before the compression. The "filter id" byte can be one of the
+ * following:
+ *
+ * 0: no filter ("copy" filter);
+ * 1: "palette" filter;
+ * 2: "gradient" filter.
+ *
+ *-- If bit 6 of the compression control byte is set to 0 (no "filter id"
+ * byte), or if the filter id is 0, then raw pixel values in the client
+ * format (see NOTE 1) will be compressed. See below details on the
+ * compression.
+ *
+ *-- The "gradient" filter pre-processes pixel data with a simple algorithm
+ * which converts each color component to a difference between a "predicted"
+ * intensity and the actual intensity. Such a technique does not affect
+ * uncompressed data size, but helps to compress photo-like images better.
+ * Pseudo-code for converting intensities to differences is the following:
+ *
+ * P[i,j] := V[i-1,j] + V[i,j-1] - V[i-1,j-1];
+ * if (P[i,j] < 0) then P[i,j] := 0;
+ * if (P[i,j] > MAX) then P[i,j] := MAX;
+ * D[i,j] := V[i,j] - P[i,j];
+ *
+ * Here V[i,j] is the intensity of a color component for a pixel at
+ * coordinates (i,j). MAX is the maximum value of intensity for a color
+ * component.
+ *
+ *-- The "palette" filter converts true-color pixel data to indexed colors
+ * and a palette which can consist of 2..256 colors. If the number of colors
+ * is 2, then each pixel is encoded in 1 bit, otherwise 8 bits is used to
+ * encode one pixel. 1-bit encoding is performed such way that the most
+ * significant bits correspond to the leftmost pixels, and each raw of pixels
+ * is aligned to the byte boundary. When "palette" filter is used, the
+ * palette is sent before the pixel data. The palette begins with an unsigned
+ * byte which value is the number of colors in the palette minus 1 (i.e. 1
+ * means 2 colors, 255 means 256 colors in the palette). Then follows the
+ * palette itself which consist of pixel values in client pixel format (see
+ * NOTE 1).
+ *
+ *-- The pixel data is compressed using the zlib library. But if the data
+ * size after applying the filter but before the compression is less then 12,
+ * then the data is sent as is, uncompressed. Four separate zlib streams
+ * (0..3) can be used and the decoder should read the actual stream id from
+ * the compression control byte (see NOTE 2).
+ *
+ * If the compression is not used, then the pixel data is sent as is,
+ * otherwise the data stream looks like this:
+ *
+ * 1..3 bytes: data size (N) in compact representation;
+ * N bytes: zlib-compressed data.
+ *
+ * Data size is compactly represented in one, two or three bytes, just like
+ * in the "jpeg" compression method (see above).
+ *
+ *-- NOTE 1. If the color depth is 24, and all three color components are
+ * 8-bit wide, then one pixel in Tight encoding is always represented by
+ * three bytes, where the first byte is red component, the second byte is
+ * green component, and the third byte is blue component of the pixel color
+ * value. This applies to colors in palettes as well.
+ *
+ *-- NOTE 2. The decoder must reset compression streams' states before
+ * decoding the rectangle, if some of bits 0,1,2,3 in the compression control
+ * byte are set to 1. Note that the decoder must reset zlib streams even if
+ * the compression type is "fill" or "jpeg".
+ *
+ *-- NOTE 3. The "gradient" filter and "jpeg" compression may be used only
+ * when bits-per-pixel value is either 16 or 32, not 8.
+ *
+ *-- NOTE 4. The width of any Tight-encoded rectangle cannot exceed 2048
+ * pixels. If a rectangle is wider, it must be split into several rectangles
+ * and each one should be encoded separately.
