Screen

Functions for drawing various things to the screen.

Note: There are no longer any fully paletted renderers in GZDoom as of version 3.5. Alternate palette index parameters are generally ignored now.

DrawChar

TODO
DrawShape

TODO
DrawText

TODO
DrawTexture

TODO
Clear

Draws a rectangle from top left to bottom right in screen coordinates of cr color. Does not support translucent colors. palcolor is a palette index to use as a color in paletted renderers or -1 for automatic conversion from the given RGB color.
Dim

Draws a rectangle at x y of w h size in screen coordinates of cr color. Does not support translucent colors, but amount may be used to specify the translucency in a range of 0-1 inclusive.
DrawFrame

Draws a frame around a rectangle at x y of w h size in screen coordinates, using the border graphics as defined in MAPINFO/GameInfo.
DrawLine

Draws a one pixel wide line from x0 y0 to x1 y1 in screen coordinates of color cr with alpha alpha (range 0-255.)
DrawThickLine

Draws a thickness pixel wide line from x0 y0 to x1 y1 in screen coordinates of color cr with alpha alpha (range 0-255.)
GetAspectRatio

Returns the aspect ratio of the screen.
GetHeight

Returns the height of the screen.
GetWidth

Returns the width of the screen.
PaletteColor

Returns a color for a given palette index.
VirtualToRealCoords

TODO
ClearClipRect

Clears the clipping rectangle if there is one.
GetClipRect

Returns the clipping rectangle's x/y/w/h.
GetViewWindow

Returns the 3D viewing window, which may be smaller than the screen size with any given screenblocks setting.
SetClipRect

Sets the clipping rectangle to restrict further drawing to the region starting at x y of size w h in screen coordinates.
