DrawInterface

Last revision: ver. 6.0 - 25 October 2014

module omega wraps omega::DrawInterface

Exposes methods to simplify drawing on 2d surfaces. Used in conjunction with setDrawFunction

Method(s)	Description
`drawRectGradient(position, size, orientation)`
`drawRect(position, size, color)`
`drawRectOutline(position, size, color)`
`drawText(text, font, position, alignFlags)`
`drawCircleOutline(position, radius, color, segments)`
`createFont(fontName, fileName, size)`
`getFont(name)`
`getDefaultFont()`
(v6.0) Shaders
`int getOrCreateProgram(string name, string vertexFile, string fragmentFile)`	Gets or creates a new shader program. If the program does not exists, attempts to create it using the two passed files as source for a vertex and a fragment shader.
`int getOrCreateProgramFromSource(string name, string vertexSource, string fragmentSource)`	Gets or creates a new shader program. If the program does not exists, attempts to create it using the two passed strings as source for a vertex and a fragment shader.
`void program(int program)`	Enables the specified program. Pass `0` to switch back to fixed pipeline drawing.
`int findUniform(int program, string name)`	Finds the program uniform with the specified name.
`void uniformFloat(int uniform, float value)`	Sets a float uniform value.

Valid align flags for drawText:
